Kavli Affiliate: George R. Ricker | First 5 Authors: Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin, Derek Buzasi, Oleg Kochukhov | Summary: The consistently low activity level of the old solar analog 51 Peg not only facilitated the discovery of the first hot Jupiter, but also led to the suggestion that the star […]
Kavli Affiliate: Sara Seager | First 5 Authors: Maxwell D. Seager, Sara Seager, William Bains, Janusz J. Petkowski, | Summary: Scientists have long speculated about the potential habitability of Venus, not at the 700K surface, but in the cloud layers located at 48-60 km altitudes, where temperatures match those found on Earth’s surface. However, the […]
Kavli Affiliate: Erin Kara | First 5 Authors: Megan Masterson, Kishalay De, Christos Panagiotou, Erin Kara, Iair Arcavi | Summary: Most tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a powerful probe of dust-enshrouded environments, and […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nadia Qutob, Razieh Emami, Kung-Yi Su, Randall Smith, Lars Hernquist | Summary: We make an in-depth analysis of different AGN jet models’ signatures, inducing quiescence in galaxies with a halo mass of $10^{12} M_odot$. Three jet models, including cosmic ray-dominant, hot thermal, and precessing kinetic jets, are […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Jakob T. Faber, Daniele Michilli, Ryan Mckinven, Jianing Su, Aaron B. Pearlman | Summary: We present the discovery of twelve thus far non-repeating fast radio burst (FRB) sources, detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These sources were selected from a database comprising […]
Kavli Affiliate: Ronald Remillard | First 5 Authors: Yanan Wang, Dheeraj R. Pasham, Diego Altamirano, Andres Gurpide, Noel Castro Segura | Summary: The tidal disruption of a star around a supermassive black hole (SMBH) offers a unique opportunity to study accretion onto a SMBH on a human-timescale. We present results from our 1000+ days NICER, […]

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Marc Basquens, Eduardo J. S. Villaseñor, , | Summary: The GNH method is used in this paper to study the Hamiltonian formulation of the Euclidean self-dual action. This action can be used to arrive at the complex Ashtekar formulation of General Relativity […]
