Electron injection into diffusive shock acceleration has been a
topic of great interest over the decades. One of the prime
candidate mechanisms, stochastic shock drift acceleration
(SSDA), has recently been discussed based on fully
kinetic...
JWST has found many more supermassive black holes (SMBHs) at
z>4 than we expected. In addition, some of these SMBHs show
spectacular properties, such as their masses given their redshifts
and host galaxy masses. Nonetheless, it is difficult to...
I will discuss the results of the second observing season of the
CO Mapping Array Project (COMAP). COMAP is a line intensity
mapping experiment seeking to probe the cosmic star formation
history by mapping the 115 GHz CO(1-0) emission line at
z~3. ...
Abstract: Axion dark matter thermalizes by gravitational
self-interactions and forms a Bose-Einstein condensate. It is
shown that the rethermalization of the axion fluid during the
initial collapse of large scale overdensities at cosmic dawn...
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.
Neutrinos are the second most abundant particle in the known
Universe yet they remain mysterious. While they played an important
role in the early Universe, today they contribute at most 1-2% of
the energy budget and leave only faint signatures. A...
