Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jubee Sohn, Margaret J. Geller, Josh Borrow, Mark Vogelsberger, | Summary: We derive the central stellar velocity dispersion function for quiescent galaxies in 280 massive clusters with $log (M_{200} / M_{odot}) > 14$ in IllustrisTNG300. The velocity dispersion function is an independent tracer of the dark matter […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Angela Adamo, Hakim Atek, Micaela B. Bagley, Eduardo Bañados, Kirk S. S. Barrow | Summary: With stunning clarity, JWST has revealed the Universe’s first billion years. The scientific community is analyzing a wealth of JWST imaging and spectroscopic data from that era, and is in the process […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: John Wendeborn, Catherine C. Espaillat, Sophia Lopez, Thanawuth Thanathibodee, Connor E. Robinson | Summary: The Classical T Tauri Star (CTTS) stage is a critical phase of the star and planet formation process. In an effort to better understand the mass accretion process, which can dictate further […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhen-Kai Gao, Chen-Fatt Lim, Wei-Hao Wang, Chian-Chou Chen, Ian Smail | Summary: We present confusion-limited SCUBA-2 450-$mu$m observations in the COSMOS-CANDELS region as part of the JCMT Large Program, SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES). Our maps at 450 and 850 $mu$m cover an area […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report the result of a search for the rare decay $B^{0} to gamma gamma$ using a combined dataset of $753times10^{6}$ $Bbar{B}$ pairs collected by the Belle experiment and $387times10^{6}$ $Bbar{B}$ pairs collected by the Belle […]

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: The BICEP/$textit{Keck}$ (BK) series of cosmic microwave background (CMB) polarization experiments has, over the past decade and a half, produced a series of field-leading constraints on cosmic inflation via measurements of the "B-mode" […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jan Scholtz, Francesco D’Eugenio, Roberto Maiolino, Pablo G. Pérez-González, Chiara Circosta | Summary: JWST is discovering increasing numbers of quiescent galaxies 1–2 billion years after the Big Bang, whose redshift, high mass, and old stellar ages indicate that their formation and quenching were surprisingly rapid. This fast-paced […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early universe. In this work, we extend previous results for GPP of […]
