Kavli Affiliate: Avi Shporer | First 5 Authors: Petr Kabáth, Priyanka Chaturvedi, Phillip J. MacQueen, Marek Skarka, Ján Šubjak | Summary: We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have orbital periods between 1.4 and 2.05 days. The masses […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Anna Frebel, Alexander P. Ji, Mohammad K. Mardini, Xiaowei Ou | Summary: We present chemical abundances and velocities of five stars between 0.3 kpc to 1.1 kpc from the center of the Tucana II ultra-faint dwarf galaxy (UFD) from high-resolution Magellan/MIKE spectroscopy. We find that […]

Kavli Affiliate: Erin Kara | First 5 Authors: Jingyi Wang, Erin Kara, Matteo Lucchini, Adam Ingram, Michiel van der Klis | Summary: We perform the first systematic search of all NICER archival observations of black hole (and candidate) low-mass X-ray binaries for signatures of reverberation. Reverberation lags result from the light travel time difference between […]

Kavli Affiliate: George Ricker | First 5 Authors: Luisa Maria Serrano, Davide Gandolfi, Alexander J. Mustill, Oscar Barragán, Judith Korth | Summary: It is commonly accepted that exoplanets with orbital periods shorter than 1 day, also known as ultra-short period (USP) planets, formed further out within their natal protoplanetary disk, before migrating to their current-day […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Giulia Despali, Levi G. Walls, Simona Vegetti, Martin Sparre, Mark Vogelsberger | Summary: We study the effect of self-interacting dark matter (SIDM) and baryons on the shapes of early-type galaxies (ETGs) and their dark matter haloes, comparing them to the predictions of the standard cold dark matter […]

Kavli Affiliate: George Ricker | First 5 Authors: George Zhou, Christopher P. Wirth, Chelsea X. Huang, Alexander Venner, Kyle Franson | Summary: The TESS mission has enabled discoveries of the brightest transiting planet systems around young stars. These systems are the benchmarks for testing theories of planetary evolution. We report the discovery of a mini-Neptune […]

Kavli Affiliate: Eric Miller | First 5 Authors: Ege Ozsar, Misha Kilmer, Eric Miller, Eric de Sturler, Arvind Saibaba | Summary: In this paper, we consider the restoration and reconstruction of piecewise constant objects in two and three dimensions using PaLEnTIR, a significantly enhanced Parametric level set (PaLS) model relative to the current state-of-the-art. The […]

Kavli Affiliate: Eric Miller | First 5 Authors: Ege Ozsar, Misha Kilmer, Eric Miller, Eric de Sturler, Arvind Saibaba | Summary: We introduce PaLEnTIR, a significantly enhanced parametric level-set (PaLS) method addressing the restoration and reconstruction of piecewise constant objects. Our key contribution involves a unique PaLS formulation utilizing a single level-set function to restore […]
