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: Paul L. Schechter | First 5 Authors: Luke Weisenbach, Timo Anguita, Jordi Miralda-Escudé, Masamune Oguri, Prasenjit Saha | Summary: Microlensing near macro-caustics is a complex phenomenon in which swarms of micro-images produced by micro-caustics form on both sides of a macro-critical curve. Recent discoveries of highly magnified images of individual stars in massive […]
