Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Simon Birrer, Elizabeth J. Buckley-Geer, Michele Cappellari, Frederic Courbin, Frederic Dux | Summary: We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar velocity dispersions measured from spectra obtained with the James Webb […]

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Kayla Owens, , | Summary: This is the second of two papers exploring the effects of metallicity on the multi-wavelength properties of Cepheids in terms of their multi-wavelength period-luminosity (PL) relations, impacting their use as extragalactic distance indicators, underpinning one […]
Kavli Affiliate: Alexander Ji | First 5 Authors: Michael R. Blanton, Joleen K. Carlberg, Tom Dwelly, Ilija Medan, S. Drew Chojnowski | Summary: We present an algorithmic method for efficiently planning a long-term, large-scale multi-object spectroscopy program. The Sloan Digital Sky Survey V (SDSS-V) Focal Plane System performs multi-object spectroscopy using 500 robotic positioners to […]
Kavli Affiliate: Stephan S. Meyer | First 5 Authors: James. H. Adams Jr., Denis Allard, Phillip Alldredge, Luis Anchordoqui, Anna Anzalone | Summary: The Extreme Universe Space Observatory on a Super Pressure Balloon 2 (EUSO-SPB2) is a pathfinder mission toward a space-based observatory such as the Probe of Extreme Multi-Messenger Astrophysics (POEMMA). The aim of […]
Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, Remi Chou, Taejoon Kim, , | Summary: The reconstruction of sparse signals from a limited set of measurements poses a significant challenge as it necessitates a solution to an underdetermined system of linear equations. Compressed sensing (CS) deals with sparse signal reconstruction using techniques such […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Xihan Ji, Vasily Belokurov, Roberto Maiolino, Stephanie Monty, Yuki Isobe | Summary: Recent JWST observations have revealed a growing population of galaxies at $z>4$ with elevated nitrogen-to-oxygen ratios. These "N/O-enhanced" galaxies (NOEGs) exhibit near- to super-solar N/O at sub-solar O/H, clearly deviating from the well-established scaling relation […]
Kavli Affiliate: John E. Carlstrom | First 5 Authors: Rohan Dahale, Ilje Cho, Kotaro Moriyama, Kaj Wiik, Paul Tiede | Summary: We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astrophysical, and imaging effects. Leveraging the enhanced capabilities of […]
