Pulsar timing arrays (PTAs) consist of a set of regularly monitored millisecond pulsars with extremely stable rotational periods. The arrival time of pulses can be altered by the passage of gravitational waves (GWs) between them and the Earth, thus...

Abstract: LUX-ZEPLIN (LZ) is a direct detection dark matter experiment currently being operated at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. The experiment utilizes a dual phase time projection chamber (TPC)  to...

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.

Star clusters are a key product of star formation. They trace the densest peaks of the star formation hierarchy, and as (effectively) single-age populations, they have great utility as “clocks” for timing various phases of the star formation cycle...

Abstract: The Kaluza-Klein theories represent the classical mathematical approach to the unification of general relativity with electromagnetism and more generally with gauge fields. In these theories, general relativity is considered in 1+3+d...

Searching for signatures of non-Gaussianity in primordial fluctuations is one of the foremost quests in modern cosmology. In my talk, I will present a novel, non-perturbative formalism to constrain the local type primordial non-Gaussianity (PNG)...

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...
