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

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 […]

The Rise of the $R$-Process in the Gaia-Sausage/Enceladus Dwarf Galaxy

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 […]

Constraining Near-Simultaneous Radio Emission from Short Gamma-ray Bursts using CHIME/FRB

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 […]

Microlensing near macro-caustics

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 […]

Photon Counting Interferometry to Detect Geontropic Space-Time Fluctuations with GQuEST

Kavli Affiliate: Lee McCuller | First 5 Authors: Sander M. Vermeulen, Torrey Cullen, Daniel Grass, Ian A. O. MacMillan, Alexander J. Ramirez | Summary: The GQuEST (Gravity from the Quantum Entanglement of Space-Time) experiment uses tabletop-scale Michelson laser interferometers to probe for fluctuations in space-time. We present an interferometer design featuring a novel photon counting […]

Tidal heating as a discriminator for horizons in equatorial eccentric extreme mass ratio inspirals

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Sayak Datta, Richard Brito, Scott A. Hughes, Talya Klinger, Paolo Pani | Summary: Tidal heating in a binary black hole system is driven by the absorption of energy and angular momentum by the black hole’s horizon. Previous works have shown that this phenomenon becomes particularly significant […]
