Kavli Affiliate: Bradford Benson | First 5 Authors: Grace Smith, Grace Smith, , , | Summary: We present a strong lensing analysis and reconstruct the mass distribution of SPT-CL J0356-5337, a galaxy cluster at redshift z = 1.034. Our model supersedes previous models by making use of new multi-band HST data and MUSE spectroscopy. We […]
Kavli Affiliate: Blake Sherwin | First 5 Authors: Boris Bolliet, Boris Bolliet, , , | Summary: These notes are very much work-in-progress and simply intended to showcase, in various degrees of details (and rigour), some of the cosmology calculations that class_sz can do. We describe the class_sz code in C, Python and Jax. Based on […]

Kavli Affiliate: Blake Sherwin | First 5 Authors: Licong Xu, Licong Xu, , , | Summary: We present a multi-agent system for automation of scientific research tasks, cmbagent (https://github.com/CMBAgents/cmbagent). The system is formed by about 30 Large Language Model (LLM) agents and implements a Planning & Control strategy to orchestrate the agentic workflow, with no […]
Kavli Affiliate: Subo Dong | First 5 Authors: Sydney Petz, Sydney Petz, , , | Summary: We search a sample of 5,685,060 isolated sources in the All Sky Automated Survey for SuperNovae (ASAS-SN) with 14.5<g<15 mag for slowly varying sources with brightness changes larger than ~0.03 mag/year over 10 years. We find 426 slowly-varying systems. […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: SDSS Collaboration, SDSS Collaboration, , , | Summary: Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial objects to constrain the physical processes that […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Juna A. Kollmeier, Juna A. Kollmeier, , , | Summary: The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the sky with multi-object spectroscopy (MOS) at telescopes in both hemispheres (the 2.5-m Sloan Foundation […]
Kavli Affiliate: Jing Wang | First 5 Authors: Hugh Roxburgh, Hugh Roxburgh, , , | Summary: We probe the atomic hydrogen (HI) emission from the host galaxies of fast radio bursts (FRBs) to investigate the emerging trend of disturbance and asymmetry in the population. Quadrupling the sample size, we detect 13 of 14 new hosts […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michelle A. Berg, Michelle A. Berg, , , | Summary: Gravitational lensing has transformed the field of gas tomography in the intergalactic medium (IGM) and circumgalactic medium (CGM). Here we use the brightest lensed galaxy identified to date, the Sunburst Arc ($z$$approx$2.37), to constrain the physical […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Callum Witten, Callum Witten, , , | Summary: Protoclusters represent the most extreme environments in the very early Universe. They form from large-scale dark matter overdensities, harbouring an overabundance of galaxies fed by large gas reservoirs. Their early and accelerated evolution results in a distinct difference in […]
