Upcoming Events

The Golden Age of Neutron Stars
Gordon Baym, University of Illinois Urbana-Champaign
Event Type: Physics Dept Colloquium
Date: Thursday, September 23, 2021
Time: 4:00 PM -
Location: 726 Broadway, 940, CCPP Seminar
Description: Neutron stars were first posited in the early thirties, and discovered as pulsars in the late sixties; however we are only recently beginning to understand the matter they contain. I will describe the ongoing development of a consistent picture of the liquid interiors of neutron stars, now driven by ever increasing observations as well as theoretical advances. These include in particular observations of three heavy neutron stars of about 2.0 solar masses and higher; ongoing simultaneous inferences of masses and radii of neutron stars by the NICER telescope; and past and future observations of binary neutron star mergers, through gravitational waves as well as across the electromagnetic spectrum. Theoretically an understanding is emerging in QCD of how nuclear matter can turn into deconfined quark matter in the interior, and be capable of supporting heavy neutron stars, which I will illustrate with a discussion of modern quark-hadron crossover equations of state.

Dwarf Galaxies and Their Black Holes
Jenny Greene, Princeton University
Event Type: Astro Seminar
Date: Tuesday, September 28, 2021
Time: 2:00 PM - 3:15 PM
Location: zoom
Description: Because they are dark-matter dominated, dwarf galaxies provide some of the most stringent tests of our cold dark matter model. Specifically, Lambda CDM makes predictions about the number, shape, and spatial distributions of the faint friends of massive galaxies. I will present results from the Exploration of Local VolumE Satellites ELVES survey, that constructs the largest sample of satellites around Milky Way-like hosts. Our ability to utilize dwarfs as tests of CDM is limited by our understanding of baryonic process; I will also discuss our efforts to us the Hyper Suprime Camera Survey to understand the role of feedback and merging in dwarf evolution. If time permits, I discuss what we know about black holes in dwarf galaxies, and how their demographics sheds light on the formation of the seeds of supermassive black holes.

Searching for New Physics in the Universes Oldest Light with the Atacama Cosmology Telescope
Colin Hill, Columbia University & CCA
Event Type: Astro Seminar
Date: Tuesday, October 12, 2021
Time: 2:00 PM - 3:30 PM
Location: 726 Broadway, 940, CCPP Seminar
Description: I will discuss recent and ongoing work focused on attempts to restore concordance amongst cosmological data sets, motivated by discrepancies amongst some measurements of the cosmic expansion rate H_0 and the matter clustering amplitude S_8. Particular attention will be paid to models invoking new physics at or prior to recombination, including quasi-accelerating early dark energy models and small-scale baryon-clumping scenarios e.g., due to primordial magnetic fields. In particular, I will discuss constraints on these models derived using the latest data from the Atacama Cosmology Telescope ACT. I will conclude with a look ahead to forthcoming CMB measurements from ACT, which will provide a powerful test of these models in the low-noise, high-resolution regime.

Yifan Wang, New York University

Alien Oceans on Earth and Beyond
Kevin Hand, Jet Propulsion Lab
Event Type: Astro Seminar
Date: Tuesday, October 19, 2021
Time: 2:00 PM - 3:30 PM
Location: 726 Broadway, 940, CCPP Seminar
Description: Where is the best place to find living life beyond Earth? It may be that the small, ice-covered moons of Jupiter and Saturn harbor some of the most habitable real estate in our Solar System. Life loves liquid water and these moons have lots of it. These alien oceans of the outer solar system have likely persisted for much of the history of the solar system and as a result they are highly compelling targets in our search for life beyond Earth. Within these oceans may reside a second origin of life itself, and the answer to whether or not we live in a biological universe, or one in which life on Earth represents a biological singularity. Dr. Hand will explain the science behind why we think we know these oceans exist and what we know about the conditions on these worlds. He will focus on Jupiter’s moon Europa, which is a top priority for future missions. Dr. Hand will also detail how the exploration of Earth’s ocean is helping to guide our understanding of the potential habitability of worlds like Europa.

Implications of the ongoing interaction between the Milky Way and the Large Magellanic Cloud for the CDM paradigm
Nico Garavito-Camargo, Flatiron CCA
Event Type: Astro Seminar
Date: Tuesday, November 16, 2021
Time: 2:00 PM - 3:15 PM
Location: 726 Broadway, 940, CCPP Seminar
Description: The ongoing interaction with the Large Magellanic Cloud LMC is revolutionizing our view of the dynamical state of the Milky. The perturbations caused by the LMC open new avenues to test the nature of dark matter. Using results from high-resolution N-body simulations, I will describe the two main perturbations caused by the LMC: the DM wake and the reflex motion. The recent discovery of the stellar wake counterpart of the DM wake opens the opportunity to test the different DM models. Furthermore, I will illustrate how the time-dependent potential of the MW--LMC system complicates efforts to recover the triaxial structure of the halo using the kinematic of the stellar halo. Finally, I will discuss how some current challenges to cold dark matter theory, such as the plane of satellites of the MW, are likely natural consequences of the MW--LMC interaction.
