Abstract: Dark matter is a hypothetical matter in the universe introduced to coherently explain observations ranging from the scale of galaxies to the whole of the universe. The DarkSide program is a direct dark matter detection experiment that...

Abstract: Cross-section predictions are crucial for the success of long-baseline neutrino experiments, but they suffer from significant theoretical uncertainties. Given the promise of future near detector data, one certainly expects and needs to...

Abstract: The accelerated expansion of the universe leads to a horizon beyond which we cannot see.  Structure arises from the quantum variance of early universe fields stretched across the horizon, according to the simplest theory fitting...

The Bahcall Lunch follow the astrophysics colloquium lecture. Registration is required by 6pm the previous Thursday so a meal can be provided. Email Amanda at cenker@ias.edu with questions.

All large-scale structure cosmologists are faced with the question: how do we robustly extract cosmological information, such as on dark energy, gravity, and inflation, from observed tracers such as galaxies whose astrophysics is extremely complex...

Abstract: I will present upcoming linear and non-linear stability results concerning the asymptotic behavior of collisionless many-particle systems on black hole exteriors. On the one hand, I will discuss the decay properties of massive Vlasov...

A signal of Local Primordial non-Gaussianity (LPNG) in the cosmological density field heralds the presence of multiple fields in the inflationary era. Optical and NIR galaxy surveys will soon exceed the sensitivity of the Cosmic Microwave Background...

Planetary-scale magnetic fields provide a unique window into a planet's deep interior. From the magnetic field of Earth to that of Jupiter, the existence of such fields is tied to the presence of an electrically conductive convecting fluid (dynamo...

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Galaxy clusters undergoing mergers host spectacular megaparsec-scale, highly polarized diffuse radio emission known as radio relics. With their enormous extent, these sources trace the largest particle accelerators in the Universe. Relics are...
