Mercury Transit Across The Sun

Now here’s something you don’t see every day. In fact, you won’t see it again until 2032!

This Monday morning, Mercury will temporarily move between the Earth and the Sun. This event is like a tiny solar eclipse, where Mercury will block part of the Sun from our perspective, and we will see Mercury move across the disk of the Sun over the course of a few hours.

Unfortunately, the transit starts before the Sun will rise, but from our vantage point in San Jose, we’ll be able to watch the last third of it.

Do not look at the Sun with your naked eyes (!) but we’ll have telescopes with special filters to make this spectacle safe to observe.

Along the way, we can also share with you a little about how the Sun works and how complex magnetic fields drive sunspots and prominences that we may get to see as well. And we’ll probably have some donuts, coffee and tea to make it easier to bear this early-morning event.

Increased Hubble tension with a new measurement of the Hubble constant using strong lensing

The recent tension between early- and late-Universe measurements of the Hubble constant highlights the necessity for independent and precise probes such as the time-delay cosmography. The measured time-delays between the lensed images of a background quasar depend on the absolute physical scales in the lens configuration. Thus, they allow measurement of these scales to infer the Hubble constant, H_0. Due to a number of great advancements over the past decade in both the data quality and modeling techniques, the measurement of H_0 from the time-delays has already become competitive with other traditional methods such as the cosmic distance ladder. This is evident from the recent 2.4% blind measurement of H_0 from only six lenses (Wong et al. 2019). Recently, I have analyzed one new lens system to infer H_0 with the highest precision from a single lens system to date. This new measurement brings the combined uncertainty from time-delay cosmography to 2% – which is comparable to the SH0ES measurement – and increases the tension with the early-Universe probes. Lastly, I will present the future roadmap of time-delay cosmography to independently reach 1% precision within a few years.

The Extremes of the Blazar Sequence

Blazars are among the most luminous, persistent, sources in our Universe. With powerful relativistic jets closely pointed to our line of sight, they are detected at high redshifts (up to z=4-5) and seem to follow the so-called `blazar sequence’, i.e. the more luminous the source, the redder their SED appears. At one end of the sequence lie the most extreme of these sources, the MeV blazars. Found when the Universe was barely 1-2 billion years old, they harbor jets with power exceeding 10^47 erg s-1 and host billion solar masses black holes, questioning our understanding of the origin and growth of supermassive black holes. At the other end, lies the undetected population of high-frequency peaked and luminous blazars. If found, such sources not only will be crucial to understand the blazar evolution, but would also be excellent probes for the Extragalactic Background Light. At present, only few such sources are known and the detection of more is crucial to shed a light on this elusive population. Using the improved sensitivity of the Fermi Large Area Telescope (LAT), combined with the incredible capabilities of NuSTAR, we studied six powerful MeV blazars beyond redshift 3. Moreover, these facilities enabled us to find one more high-frequency high-luminosity BL Lac and study its properties in the broader blazar population scheme. Here, we present the results of our recent work on some of the most powerful and distant blazars ever detected.

Simulation shows that a sample of nine lenses shrinks the uncertainty on this measurement to 2% (Shajib et al. 2018). I will present the Hubble constant measured from a newly analyzed lens system taking the sample size to seven. In addition, I will present the future roadmap of time-delay cosmography to independently reach 1% precision within a few years.

Meet the Neighbors: Planetary Systems Orbiting Nearby Stars

The NASA Kepler mission revealed that our Galaxy is teeming with planetary systems and that Earth-sized planets are common. However, most of the planets detected by Kepler orbit stars too faint to permit detailed study. The NASA Transiting Exoplanet Survey Satellite (TESS,) launched in 2018, is finding hundreds of small planets orbiting stars that are much closer and brighter. Dr. Dressing will describe the TESS mission and explain how analyses of the TESS planets will allow us to probe the composition of small planets, investigate the formation of planetary systems, and set the stage for the next phase of exoplanet exploration: the quest for the signatures of life in the atmospheres of strange new worlds.

What Happens When a Massive Star Fails (Sort of) to Explode?

There are observational and theoretical reasons to suspect that up to 10s of percent of massive stars that undergo core-collapse at the end of their lives fail to explode in a canonical energetic supernova explosion. In this talk I will describe what transpires in such nominally failed supernovae and its importance for understanding the masses and spins of black holes (e.g., detected by LIGO). I will also describe how ‘failed’ supernovae may manifest themselves observationally in time-domain surveys.

Cosmochemical constraints on the earliest evolution of the Solar System

Cosmochemistry, the study of chemical and isotopic signatures of meteorites, can provide direct constraints on the origin and evolution of the Solar System. As a discipline, it therefore, represents an important complement to fields like astronomy and astrophysics. Here I will review recent developments in cosmochemistry, and discuss several important implications for the dynamics of the early Solar System. From a cosmochemist’s viewpoint, the evolution of the solar protoplanetary disk started with the formation of the oldest dated solids, Ca-Al-rich inclusions (CAIs), which formed ~4567 billion years ago. A second important step in early Solar System evolution is the formation of the first ~km-sized bodies known as planetesimals. Recent isotope studies of iron meteorites-metal samples of small planetesimal cores-demonstrate that core segregation in their parent bodies occurred within the first ~1-3 million years (Myr) after CAIs. Consequently, the formation of iron meteorite parent bodies occurred even earlier, well within <1 Ma of Solar System formation, demonstrating that planetesimals formed very early. Recent work has shown that meteorites exhibit a fundamental isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC) groups, which most likely represent material from the inner and outer Solar System, respectively. The NC-CC dichotomy combined with the ages of meteorites mandate an early and prolonged spatial separation of inner (NC) and outer (CC) solar protoplanetary disk reservoirs, lasting between ~1 and ~4 Myr after Solar System formation. This is most easily reconciled with the early and rapid growth of Jupiter's core, inhibiting significant exchange of material from inside and outside its orbit. An important consequence of this finding is that Jupiter is the oldest planet of the Solar System and its solid core must have formed well within <1 Ma after CAIs.

Over many decades, we have collected overwhelming evidence for the existence of dark matter in the universe. Some of the strongest evidence comes from observations of the growth of galaxies and clusters of galaxies, from tiny clumps of matter at the earliest times to the vast patterns of stellar structures that we see in our telescopes today. These patterns are created by streams of dark matter coming together under the influence of their gravitational attraction. There are new ideas about dark matter in which these streams are not completely dark but, rather, can be coaxed into revealing themselves as they shine ever so faintly. This talk will review our knowledge of dark matter, and describe new methods for revealing its flow being developed here at SLAC.

Thirty-five years ago, a group of entrepreneurs and scientists founded the SETI Institute �" the first scientific institute dedicated to the search for extraterrestrial life in the universe. We’re excited to commemorate this anniversary. We invited SETI Institute co-founder Jill Tarter and 2018 Drake Award Recipient Vikki Meadows to discuss the challenges and possible future strategies for the detection of life. Initiated by Jill Tarter in 1990s, Project Phoenix marked the first systematic search for technosignatures. Today, the Allen Telescope Array and Laser SETI are driving our technosignature search. The discovery that exoplanets are common has radically changed our view of the universe. The likelihood that there are habitable worlds elsewhere in the universe seems more plausible than ever before. Astronomers, including Vikki Meadows, are developing new instruments to help search for life on other planets. By analyzing data from exoplanets and identifying biosignatures, we will be able to search for habitable planets and the presence of life. Which approach will discover the first evidence of extraterrestrial life? Will technosignatures or biosignatures confirm our hypothesis that life exists outside our watery, shimmering planet and that, indeed, we are not alone?
