Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Dominique Sluse, Erik A. Zaborowski, Alex Drlica-Wagner, Cameron Lemon | Summary: A quadruply lensed source, J125856.3-031944, has been discovered using the DELVE survey and WISE W1 – W2 colors. Followup direct imaging carried out with the MPIA 2.2 m and the Baade 6.5 […]
Kavli Affiliate: Lee McCuller | First 5 Authors: James W. Gardner, Tuvia Gefen, Simon A. Haine, Joseph J. Hope, John Preskill | Summary: Although measuring the deterministic waveform of a weak classical force is a well-studied problem, estimating a random waveform, such as the spectral density of a stochastic signal field, is much less well-understood […]
Kavli Affiliate: Erin Kara | First 5 Authors: Minghao Yue, Anna-Christina Eilers, Tonima Tasnim Annana, 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 […]

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 […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Alexander P. Ji, Anna Frebel, Rohan P. Naidu, Guilherme Limberg | Summary: Neutron star mergers (NSMs) produce copious amounts of heavy r-process elements after a time delayed inspiral process. Once NSMs are present in a galaxy, r-process elements, such as Eu, are expected to significantly […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Alice P. Curtin, Sloane Sirota, Victoria M. Kaspi, Shriharsh P. Tendulkar, Mohit Bhardwaj | Summary: We use the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Fast Radio Burst (FRB) Project to search for FRBs that are temporally and spatially coincident with gamma-ray bursts (GRBs) occurring between 2018 […]
