BASS. XLIII: Optical, UV, and X-ray emission properties of unobscured Swift/BAT active galactic nuclei

Posted by dbos September 18, 2024Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Kriti K. Gupta, Claudio Ricci, Matthew J. Temple, Alessia Tortosa, Michael J. Koss | Summary: We present one of the largest multiwavelength studies of simultaneous optical-to-X-ray spectral energy distributions (SEDs) of unobscured active galactic nuclei (AGN) in the local Universe. Using a representative sample of hard-X-ray-selected AGN […]

SAGAbg II: the Low-Mass Star-Forming Sequence Evolves Significantly Between 0.05<z<0.21

Posted by dbos September 18, 2024Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Erin Kado-Fong, Marla Geha, Yao-Yuan Mao, Mithi A. C. de los Reyes, Risa H. Wechsler | Summary: The redshift-dependent relation between galaxy stellar mass and star formation rate (the Star-Forming Sequence, or SFS) is a key observational yardstick for galaxy assembly. We use the SAGAbg-A sample […]

SPECTER: An Instrument Concept for CMB Spectral Distortion Measurements with Enhanced Sensitivity

Posted by dbos September 18, 2024September 30, 2024Chicago

Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Alina Sabyr, Carlos Sierra, J. Colin Hill, Jeffrey J. McMahon, | Summary: Deviations of the cosmic microwave background (CMB) energy spectrum from a perfect blackbody uniquely probe a wide range of physics, ranging from fundamental physics in the primordial Universe ($mu$-distortion) to late-time baryonic feedback processes […]

The Faraday rotation measure of the M87 jet at 3.5mm with the Atacama Large Millimeter/submillimeter Array

Posted by dbos September 18, 2024September 30, 2024Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Sijia Peng, Ru-Sen Lu, Ciriaco Goddi, Thomas P. Krichbaum, Zhiyuan Li | Summary: Faraday rotation is an important probe of the magnetic fields and magnetized plasma around active galactic nuclei (AGN) jets. We present a Faraday rotation measure image of the M87 jet between 85.2 GHz and […]

Symmetry-Based Structured Matrices for Efficient Approximately Equivariant Networks

Posted by dbos September 18, 2024September 30, 2024Chicago

Kavli Affiliate: Brian D. Nord | First 5 Authors: Ashwin Samudre, Mircea Petrache, Brian D. Nord, Shubhendu Trivedi, | Summary: There has been much recent interest in designing symmetry-aware neural networks (NNs) exhibiting relaxed equivariance. Such NNs aim to interpolate between being exactly equivariant and being fully flexible, affording consistent performance benefits. In a separate […]

A search for persistent radio sources toward repeating fast radio bursts discovered by CHIME/FRB

Posted by dbos September 17, 2024MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adaeze L. Ibik, Maria R. Drout, Bryan M. Gaensler, Paul Scholz, Navin Sridhar | Summary: The identification of persistent radio sources (PRSs) coincident with two repeating fast radio bursts (FRBs) supports FRB theories requiring a compact central engine. However, deep non-detections in other cases highlight the […]
