BOSS-CLAM: Utilizing a Constrained Linear Absorption Model to Infer Stellar Parameters from BOSS Spectra
Ilija Medan, Andrew R. Casey, Alexander P. Ji +13
Large spectroscopic surveys require robust pipelines capable of inferring stellar parameters over a wide range of the Hertzsprung-Russell (HR) diagram from data of varying quality.…
AGN Feedback Models and AGN Demographics II: Comparing Predictions of Radiative and Total Feedback to Observations
Arjun Suresh, Michael R. Blanton
We evaluate the radiative-mode active galactic nucleus (AGN) feedback models of EAGLE, SIMBA, and TNG100 by comparing their predictions for the AGN-host galaxy relationship to new…
Milky Way Mapper decoded abundances -- II: From patterns to paths
Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15
The element abundances of Milky Way disc stars encode entangled imprints of multiple enrichment processes, making it difficult to uncover the underlying chemical evolution. Here we…
Milky Way Mapper decoded abundances -- I. Shared disc enrichment patterns
Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15
Elemental abundances in the Milky Way disc trace its star-formation and enrichment history, but predicting these abundances from theory is limited by uncertain nucleosynthetic yiel…
The Eddington Ratio Distribution of Narrow Line Active Galactic Nuclei
Michael R. Blanton, Arjun Suresh, Kyle B. Westfall +2
We measure the Eddington ratio distribution of local optical narrow-line active galactic nuclei (AGN) as a function of host galaxy properties, as a potential test of galaxy formati…
AGN Feedback Models and AGN Demographics I: Radio-Mode AGN in EAGLE, SIMBA and TNG100 are Inconsistent with Observations
Arjun Suresh, Michael R. Blanton, Douglas Rennehan
We compare predictions of how Active Galactic Nuclei (AGN) populate host galaxies at low redshifts to observations, finding large discrepancies between cosmological simulation pred…
