Collisions of red giants in galactic nuclei
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Taeho Ryu, Pau Amaro Seoane, Andrew M. Taylor, Sebastian T. Ohlmann, | Summary: In stellar-dense environments, stars can collide with each other. For collisions close to a supermassive black hole (SMBH), the collisional kinetic energy can be so large that the colliding stars can be completely […]

Antiadiabatic Small Polaron Formation in the Charge Transfer Insulator ErFeO3
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ye-Jin Kim, Jocelyn L. Mendes, Young Jai Choi, Scott K. Cushing, | Summary: Small polaron formation is dominant across a range of condensed matter systems. Small polarons are usually studied in terms of ground-state transport and thermal fluctuations, but small polarons can also be created impulsively […]

Probing the Galactic Halo with RR Lyrae Stars — V. Chemistry, Kinematics, and Dynamically Tagged Groups
Kavli Affiliate: Huawei Zhang | First 5 Authors: Jonathan Cabrera Garcia, Timothy C. Beers, Yang Huang, Xin-Yi Li, Gaochao Liu | Summary: We employ a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from the newly calibrated $P$–$phi_{31}$–$R_{21}$–[Fe/H] and $Gaia$ $G$-band $P$–$R_{21}$–[Fe/H] absolute magnitude-metallicity relations of Li et al., combined […]

Six-Point AdS Gluon Amplitudes from Flat Space and Factorization
Kavli Affiliate: Xinan Zhou | First 5 Authors: Luis F. Alday, Vasco Gonçalves, Maria Nocchi, Xinan Zhou, | Summary: We present a powerful new approach to compute tree-level higher-point holographic correlators. Our method only exploits the flat-space limit, where we point out a novel and important simplification, and factorization of amplitudes in AdS. In particular, […]

TOI 4201 b and TOI 5344 b: Discovery of Two Transiting Giant Planets Around M Dwarf Stars and Revised Parameters for Three Others
Kavli Affiliate: Alan M. Levine | First 5 Authors: J. D. Hartman, G. Á. Bakos, Z. Csubry, A. W. Howard, H. Isaacson | Summary: We present the discovery from the TESS mission of two giant planets transiting M dwarf stars: TOI 4201 b and TOI 5344 b. We also provide precise radial velocity measurements and […]

Current status and desired accuracy of the isotopic production cross-sections relevant to astrophysics of cosmic rays II. Fluorine to Silicon (and updated LiBeB)
Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Yoann Génolini, David Maurin, Igor V. Moskalenko, Michael Unger, | Summary: High-precision cosmic-ray data from ongoing and recent past experiments (Voyager, ACE-CRIS, PAMELA, ATIC, CREAM, NUCLEON, AMS-02, CALET, DAMPE) are being released in the tens of MeV/n to multi-TeV/n energy range. Astrophysical and dark matter interpretations […]

A massive hot Jupiter orbiting a metal-rich early-M star discovered in the TESS full frame images
Kavli Affiliate: Roland Vanderspek | First 5 Authors: Tianjun Gan, Charles Cadieux, Farbod Jahandar, Allona Vazan, Sharon X. Wang | Summary: Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these extreme systems remains under debate for decades. With the help of […]

An Exploration of AGN and Stellar Feedback Effects in the Intergalactic Medium via the Low Redshift Lyman-$α$ Forest
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Megan Taylor Tillman, Blakesley Burkhart, Stephanie Tonnesen, Simeon Bird, Greg L. Bryan | Summary: We explore the role of galactic feedback on the low redshift Lyman-$alpha$ (Ly$alpha$)~forest ($z lesssim 2$) statistics and its potential to alter the thermal state of the intergalactic medium. Using the Cosmology and […]
