Galaxy formation in the first billion years mark a time of great
upheaval in our cosmic history: the first sources of light in the
Universe, these galaxies ended the 'cosmic dark ages' and produced
the first...
Abstract: I will recall steps taken here
at Princeton that led from the schematic physics of the cosmology I
encountered in the mid-1960s to the present well-tested LCDM
theory, and offer some lessons from the past on the future of
research in...
The physics of a magnetically confined, radiation pressure
supported column of plasma plays a defining role in understanding
the observations of accretion-powered X-ray pulsars, including
pulsating ultraluminous X-ray sources (ULXs). Near the...

Interpreting observations of the universe’s most energetic
phenomena requires a detailed understanding of particle
acceleration in astrophysical environments. In particular, these
accelerated particles, or cosmic rays, are responsible for
non...
The Bahcall Lunch follow the astrophysics colloquium
lecture. Registration is required by 3pm the previous
Friday so a meal can be provided. Please contact Amanda
Cenker with questions.
