Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Joseph F. Hennawi, Frederick B. Davies, Robert A. Simcoe, | Summary: The extents of proximity zones of high-redshift quasars enable constraints on the timescales of quasar activity, which are fundamental for understanding the growth of the supermassive black holes (SMBHs) that power the quasars’ […]
Kavli Affiliate: George Ricker | First 5 Authors: Étienne Artigau, Guillaume Hébrard, Charles Cadieux, Thomas Vandal, Neil J. Cook | Summary: We present the discovery of an $18.5pm0.5$M$_{rm Jup}$ brown dwarf (BD) companion to the M0V star TOI-1278. The system was first identified through a percent-deep transit in TESS photometry; further analysis showed it to […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Claire Guépin, Roberto Aloisio, Luis A. Anchordoqui, Austin Cummings, John F. Krizmanic | Summary: High to ultrahigh energy neutrino detectors can uniquely probe the properties of dark matter $chi$ by searching for the secondary products produced through annihilation and/or decay processes. We evaluate the sensitivities to […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ziggy Pleunis, Deborah C. Good, Victoria M. Kaspi, Ryan Mckinven, Scott M. Ransom | Summary: We present a synthesis of fast radio burst (FRB) morphology (the change in flux as a function of time and frequency) as detected in the 400-800 MHz octave by the FRB […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Masoud Rafiei-Ravandi, Kendrick M. Smith, Dongzi Li, Kiyoshi W. Masui, Alexander Josephy | Summary: The CHIME/FRB Project has recently released its first catalog of fast radio bursts (FRBs), containing 492 unique sources. We present results from angular cross-correlations of CHIME/FRB sources with galaxy catalogs. We find […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, :, Mandana Amiri, Bridget C. Andersen, Kevin Bandura | Summary: We present a catalog of 536 fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project between 400 and 800 MHz from 2018 July 25 to […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Neil D. Barrie, Chengcheng Han, Hitoshi Murayama, , | Summary: We find that the triplet Higgs of the Type II seesaw mechanism can simultaneously generate the neutrino masses and observed baryon asymmetry, while playing a role in inflation. We survey the allowed parameter space and determine that […]
Kavli Affiliate: Xian Chen | First 5 Authors: Yi Gong, Zhoujian Cao, Xian Chen, , | Summary: Binary black hole may form near a supermassive black hole. The background black hole (BH) will affect the gravitational wave (GW) generated by the binary black hole. It is well known that the Penrose process may provide extra […]
Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Tobias Dyckerhoff, Mikhail Kapranov, Vadim Schechtman, Yan Soibelman, | Summary: We develop the theory of semi-orthogonal decompositions and spherical functors in the framework of stable $infty$-categories. Building on this, we study the relative Waldhausen S-construction $S_bullet(F)$ of a spherical functor $F$ and equip it with a natural […]
Kavli Affiliate: Saul Rappaport | First 5 Authors: Zachary P. Vanderbosch, Saul Rappaport, Joseph A. Guidry, Bruce L. Gary, Simon Blouin | Summary: We present follow-up photometry and spectroscopy of ZTF J0328$-$1219 strengthening its status as a white dwarf exhibiting transiting planetary debris. Using TESS and Zwicky Transient Facility photometry, along with follow-up high speed […]
