Clearing up our FOGGIE Understanding of how UVB Models Affect Circumgalactic Medium Absorbers
Today’s paper explores how ionization from different UVB models affects mock observations from simulations of the Circumgalactic Medium.
UR: Analysis of a Sample of High Redshift, High Luminosity FeLoBAL Quasars
In the latest of our #UndergradResearch series, discover Julianna Voelker’s research on the role of quasars in galaxy evolution.
“Cool metal gas search!” Thanks! It was automated.
Today’s paper takes a look at the metal-rich gas surrounding galaxies using a million quasars from SDSS.
UR #22: FeLoNet: Using Synthetic Training Data and a Convolutional Neural Network to Classify Quasar Spectra
Today’s undergraduate research post is on very unique quasars — and how to find them!
It’s a gas gas gas: understanding gas motions surrounding galaxies
Background quasars allow us to probe the relationship between a galaxy and its gas. Today’s paper uses simulations to model such observations.
Grab the vacuum cleaner… it’s cosmic DUST!
Dust is really ubiquitous in the Universe: it is everywhere from our Solar System to stars and the interstellar medium. However, the observations of dust in galaxies fall short of the prediction of how much dust there is in the Universe. In this work, the authors try to alleviate this problem by estimating the amount of dust present in clouds of gas that inhabit galaxy halos while they look for clues regarding the origin of these clouds.
