Kavli Affiliate: Susan E. Clark | First 5 Authors: George Halal, Susan E. Clark, Ari Cukierman, Dominic Beck, Chao-Lin Kuo | Summary: Filamentary structures in neutral hydrogen (HI) emission are well aligned with the interstellar magnetic field, so HI emission morphology can be used to construct templates that strongly correlate with measurements of polarized thermal […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Alessandro Di Marco, Fabio La Monaca, Juri Poutanen, Thomas D. Russell, Alessio Anitra | Summary: This paper reports the first detection of polarization in the X-rays for atoll-source 4U 1820-303, obtained with the Imaging X-ray Polarimetry Explorer (IXPE) at 99.999% confidence level (CL). Simultaneous polarimetric measurements […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: ChangHoon Hahn, Jessica Nicole Aguilar, Shadab Alam, Steven Ahlen, David Brooks | Summary: We present the probabilistic stellar mass function (pSMF) of galaxies in the DESI Bright Galaxy Survey (BGS), observed during the One-Percent Survey. The One-Percent Survey was one of DESI’s survey validation programs conducted […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Sihan Yuan, Hanyu Zhang, Ashley J. Ross, Jamie Donald-McCann, Boryana Hadzhiyska | Summary: We present the first comprehensive Halo Occupation Distribution (HOD) analysis of the DESI One-Percent survey Luminous Red Galaxy (LRG) and Quasi-Stellar Object (QSO) samples. We constrain the HOD of each sample and test […]

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Lindsay Glesener, Albert Y. Shih, Amir Caspi, Ryan Milligan, Hugh Hudson | Summary: Understanding the nature of energetic particles in the solar atmosphere is one of the most important outstanding problems in heliophysics. Flare-accelerated particles compose a huge fraction of the flare energy budget; they have large […]

Kavli Affiliate: Robert Cameron | First 5 Authors: Charlotte M. Norris, Yvonne C. Unruh, Veronika Witzke, Sami K. Solanki, Natalie A. Krivova | Summary: Magnetic features on the surface of stars, such as spots and faculae, cause stellar spectral variability on time-scales of days and longer. For stars other than the Sun, the spectral signatures […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Enia Xhakaj, Alexie Leauthaud, Johannes Lange, Elisabeth Krause, Andrew Hearin | Summary: We propose that observations of super-massive galaxies contain cosmological constraining power similar to conventional cluster cosmology, and we provide promising indications that the associated systematic errors are comparably easier to control. We consider a […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Abel L. Peirson, Michela Negro, Ioannis Liodakis, Riccardo Middei, Dawoon E. Kim | Summary: We report the first $> 99%$ confidence detection of X-ray polarization in BL Lacertae. During a recent X-ray/$gamma$-ray outburst, a 287 ksec observation (2022 November 27-30) was taken using the Imaging X-ray […]
