Some Constructive Feedback on Feedback Models

Some Constructive Feedback on Feedback Models

by Ryan Golant | Mar 17, 2022 | Daily Paper Summaries

For the first time, astronomers have detected the hot, diffuse circumgalactic medium — a perfect testbed for models of galactic feedback. So, how do our current models stack up against the new data?

A Gamma-Ray Blast from the Distant Past

A Gamma-Ray Blast from the Distant Past

by Ryan Golant | Feb 25, 2022 | Daily Paper Summaries

GRB 210905A is one of the longest, most distant, most energetic, and most luminous gamma-ray bursts that we’ve ever detected. What can we learn from this outstanding outburst?

An Intracluster Investigation via Radio Rotation

An Intracluster Investigation via Radio Rotation

by Ryan Golant | Feb 19, 2022 | Daily Paper Summaries

How have magnetic fields in galaxy clusters evolved throughout cosmic history, and what can these fields tell us about magnetism in the early Universe? Thanks to a few tricks from radio astronomy, today’s authors have some answers.

A New Recipe for Neutron Star Magnetic Fields

A New Recipe for Neutron Star Magnetic Fields

by Ryan Golant | Nov 30, 2021 | Daily Paper Summaries

How do neutron stars acquire such strong magnetic fields? Why do these fields differ between pulsars and magnetars? Today’s paper suggests that *convective dynamos* may be at play.

Baby B-fields from the Big Bang and Beyond

Baby B-fields from the Big Bang and Beyond

by Ryan Golant | Oct 5, 2021 | Daily Paper Summaries

Cosmic magnetic fields are everywhere, but we don’t know where they came from. Today’s paper looks at simulations of the earliest fields in the Universe to try to solve this magnetic mystery.
