Stacking X-ray Observations of “Little Red Dots”: Implications for their AGN Properties

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Minghao Yue, Anna-Christina Eilers, Tonima Tasnim Ananna, Christos Panagiotou, Erin Kara | Summary: Recent {em James Webb Space Telescope (JWST)} observations have revealed a population of compact extragalactic objects at $zgtrsim4$ with red near-infrared colors, which have been dubbed as “Little Red Dots" (LRDs). The spectroscopically-selected LRDs […]

Atacama Large Aperture Submillimeter Telescope mbox{(AtLAST)} Science: Probing the Transient and Time-variable Sky

Posted by dbos Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: John Orlowski-Scherer, Thomas J. Maccarone, Joe Bright, Tomasz Kaminski, Michael Koss | Summary: The study of transient and variable events, including novae, active galactic nuclei, and black hole binaries, has historically been a fruitful path for elucidating the evolutionary mechanisms of our universe. The study of such […]

The James Webb Interferometer: Space-based interferometric detections of PDS 70 b and c at 4.8 $μ$m

Posted by Peking

Kavli Affiliate: Ruobing Dong | First 5 Authors: Dori Blakely, Doug Johnstone, Gabriele Cugno, Anand Sivaramakrishnan, Peter Tuthill | Summary: We observed the planet-hosting system PDS 70 with the James Webb Interferometer, JWST’s Aperture Masking Interferometric (AMI) mode within NIRISS. Observing with the F480M filter centered at 4.8 $mu$m, we simultaneously fit geometrical models to […]

OGLE-2015-BLG-0845L: A low-mass M dwarf from the microlensing parallax and xallarap effects

Posted by dbos MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Zhecheng Hu, Wei Zhu, Andrew Gould, Andrzej Udalski, Takahiro Sumi | Summary: We present the analysis of the microlensing event OGLE-2015-BLG-0845, which was affected by both the microlensing parallax and xallarap effects. The former was detected via the simultaneous observations from the ground and Spitzer, and the […]

Improved Thermal Resummation for Multi-Field Potentials

Posted by Chicago

Kavli Affiliate: Marcela Carena | First 5 Authors: Henning Bahl, Marcela Carena, Aurora Ireland, Carlos E. M. Wagner, | Summary: The resummation of large thermal corrections to the effective potential is mandatory for the accurate prediction of phase transitions. We discuss the accuracy of different prescriptions to perform this resummation at the one- and two-loop […]
