CAS: A Causal Attribution Score for Local and Global Explainable Artificial Intelligence
Michael Georgiades, Charalambia Varnava
Predictive explanation methods attribute a model output; they do not, by themselves, attribute an intervention effect on the real-world outcome. We introduce the Causal Attribution…
The Extended Mapping Obscuration to Reionization with ALMA (Ex-MORA) Survey: A Molecular Gas Line Search
V. Catán, J. González-López, M. Aravena +9
Current investigations of cold gas in the interstellar medium face selection biases, as optical/near-infrared surveys favor massive, low-obscuration galaxies and miss gas-rich pass…
Dust in the Average Galaxy: Attenuation, Emission, and Opacity from
Caitlin M. Casey, Hollis B. Akins, Andrew J. Battisti +43
We present constraints on the dust emission and attenuation properties of galaxies across 0<z<7 using JWST imaging from the COSMOS-Web Survey combined with deep FIR/(sub)millimeter…
The GlimmIr: Spectroscopic Variability in a z~7 LRD Indicates Rapid Changes in Both the Narrow and Broad Line Regions
Erini Lambrides, Taylor A. Hutchison, Rebecca L. Larson +39
The enigmatic population of ``Little Red Dots'' (LRDs) sit at the center of some of the largest debates in extragalactic astronomy today. The source(s) of ionizing emission and the…
The case for super-Eddington accretion in JWST broad-line AGN during the first billion years
Erini Lambrides, Rebecca Larson, Kristen Garofali +23
A multitude of JWST studies reveal a surprising over-abundance of over-massive accreting super-massive black holes (SMBHs) -- leading to a deepening tension between theory and obse…
ALMA and JWST Identification of Faint Dusty Star-Forming Galaxies up to z~8
Jorge A. Zavala, Andreas L. Faisst, Manuel Aravena +44
We exploit a new sample of around 400 bright dusty galaxies from the ALMA CHAMPS Large Program, together with the rich JWST multi-band data products in the COSMOS field, to explore…
