Abstract: Astrophysical black holes are known
to be rotating. Within classical General Relativity, the simplest
spacetime solution (the Kerr solution) describing a rotating black
hole reveals a traversable passage through an inner horizon – which
in...
The demography of young and mature exoplanets is crucial to
understanding the full picture of planetary system formation and
evolution. In this talk, I will highlight two observational
approaches that expand the exoplanet demographic census. In
the...
The Thirty Meter Telescope is a top-ranked priority of the Astro
2020 Decadal Survey because its combination of very large aperture
and adaptive optics opens up vast areas for unique observational
work across a broad swath of frontier science...
Supermassive black holes at the centers of galaxies present
unsolved theoretical challenges for our understanding of
high-energy astrophysics, gravity and gravitational waves, star and
galaxy formation, and space plasma physics. For decades, our...
The Gaia astrometric survey has delivered a detailed “close-up”
of our Galaxy, the Milky Way, by measuring precise 3D positions and
velocities for over a billion stars. This view has upended plans
for a new era of “precision Galactic dynamics.”...
Abstract: The large-scale structure of our
Universe is well described by a model in which matter is
predominantly Cold Dark Matter (CDM). While CDM was initially
thought to have trouble reproducing the small scales of our
Universe (dwarf galaxies...
The Bahcall Lunch follows the astrophysics colloquium lecture.
Registration is required by 4pm the previous Thursday so a meal can
be provided. Email Amanda at cenker@ias.edu
with questions.
There is a revolution afoot in our understanding of supermassive
black holes (SMBHs), that is reshaping our view of their formation,
growth and influence on cosmic architecture. This talk will
spotlight three recent breakthroughs that have enriched...
Primordial magnetic fields (PMFs) offer a simple explanation for
the origin of galactic magnetic fields as well as of the
purportedly detected magnetic fields in cosmic voids. In the talk,
I discuss how PMFs' influence on structure formation can...
