Illuminating the Chemistry of Planet Formation with X-ray Flares

11:30 am – 12:30 pm (CDT)MIST M102

Speaker: Ilse Cleeves (University of Virginia)

The chemistry of protoplanetary disks sets the initial composition of newly formed planets and may also regulate the efficiency by which planets form. Disk chemical abundances typically evolve over timescales spanning thousands if not millions of years. Consequently, it was a surprise when ALMA observations taken over the course of a single year showed ... read more  »

The Milky Way in the Era of Large Surveys

11:30 am – 12:30 pm (CDT)

Speaker: Jo Bovy (University of Toronto)Host: Stephanie Ho

For over a hundred years, the Milky Way has been the nexus between many fields of astrophysics, linking together investigations into the formation of planetary systems and stars to studies of galactic evolution, cosmology, and astroparticle physics. Obtaining a detailed understanding of our Galaxy’s structure, formation, and evolution is therefore cru... read more  »

Higgs Boson: The Next Generation

4:00 pm – 5:00 pm (CDT)

Speaker: Andrew Brinkerhoff (Baylor University)Host: Doojin Kim

In 2018 the LHC finished its longest operations run to date, colliding 44 million billion protons at world-record energies over the course of 3 years.  The CMS and ATLAS experiments have used this data to study the interactions of the Higgs with second generation fermions.  In summer 2020, both collaborations completed their analyses of Higgs decays t... read more  »

The Smallest and Faintest Galaxies: Clues to the Nature of Dark Matter and Galaxy Formation

11:30 am – 12:30 pm (CDT)

Speaker: Burcin Mutlu-Pakdil (University of Chicago)Host: Jonelle Walsh

The smallest and faintest galaxies around the Milky Way are the most ancient, most metal-poor, and most dark-matter-dominated systems known. These extreme objects offer unique access to small scales where the stellar and dark matter content can be studied simultaneously and hold the promise of major breakthroughs in understanding the nature of dark mat... read more  »

Mapping the Cool CGM at z≈1

11:30 am – 12:30 pm (CDT)

Speaker: Johannes Zabl (Centre de Recherche Astrophysique de Lyon)Host: Stephanie Ho

Galaxies are believed to evolve regulated by the flows of gas from and to the surrounding circumgalactic medium (CGM). However, directly observing these circumgalactic gas flows around typical galaxies in the distant Universe remains a challenge. While the low-density gas can be studied in background quasar sight-lines, large samples of galaxy-abs... read more  »

Neutrinos from Primordial Black Holes: An Unexpected Interplay

4:00 pm – 5:00 pm (CDT)

Speaker: Yuber F. Perez Gonzalez (Northwestern University and Fermilab)Host: Doojin Kim

Hawking radiation offers a unique method of neutrino production, unlike any weak interaction process. In fact, black hole evaporation depends on whether neutrinos are Dirac or Majorana, providing a different phenomenology in each case. If neutrinos are Dirac particles, the emission of the light right-handed states does not suffer from the helicity suppr... read more  »

Watch Video Shining New Light on the Physics of Neutron Star Mergers

3:15 pm – 4:15 pm (CDT)Streaming Live

Speaker: Brian Metzger (Columbia University)Host: Jeremy Holt

In August 2017, the LIGO/Virgo observatory detected gravitational waves for the first time from the merger of two neutron stars. This cataclysmic event was followed (within seconds) by a burst of gamma-rays and (within 11 hours) by a bright but rapidly-fading optical wavelength transient. The properties of the optical/IR emission matched remarkably well... read more  »

Speaker: Vinod Menon (City University of New York)Host: Alexey Belyanin

Two-dimensional (2D) van der Waals materials have emerged as a very attractive class of optoelectronic material due to the unprecedented strength in its interaction with light. In this talk I will first discuss the formation of exciton-polaritons [1] and their spin-optic control [2, 3] in the 2D transition metal dichacogenide (TMD) systems. Following th... read more  »

Deciphering the Kinematic Structure of the Small Magellanic Cloud in the Age of HST and Gaia

11:30 am – 12:30 pm (CDT)

Speaker: Paul Zivick (Texas A&M University)

Our picture of the Magellanic Clouds has undergone continuous evolution over the last few decades as we have entered into a new era of astrometry. Nearly 15 years ago, Hubble Space Telescope (HST) observations of the Clouds revealed they were likely on their first infall into the Milky Way, upending conventional wisdom surrounding them. Since then, with... read more  »

Speaker: Ivan Martinez Soler (Northwestern University and Fermilab)Host: Doojin Kim

The recent discovery of coherent neutrino-nucleus scattering (CEvNS) has opened a new venue to study neutrino physics. Although experimentally challenging because the neutrino transfers a small amount of momentum to the nucleus, there are already several experimental proposals to measure such interaction with neutrinos from nuclear reactors. In this tal... read more  »

Speaker: Danielle Berg (University of Texas Austin)Host: Stephanie Ho

In the last few years, our first glimpse of the spectral properties of z∼5−7 galaxies has emerged. Deep UV spectra have revealed prominent high-ionization nebular emission lines (i.e., C IV, He II, C III]) indicating that extreme radiation fields may be characteristic of reionization-era systems. While such strong high-ionization emission lines are ... read more  »
