No thick carbon dioxide atmosphere on the rocky exoplanet TRAPPIST-1 c

Kavli Affiliate: Laura Schaefer | First 5 Authors: , , , , | Summary: Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System (Gillon et al., 2017). Thanks to the recent launch of JWST, possible atmospheric constituents such as carbon […]

Filamentary Dust Polarization and the Morphology of Neutral Hydrogen Structures

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 (H I) emission are well-aligned with the interstellar magnetic field, so H I emission morphology can be used to construct templates that strongly correlate with measurements of polarized […]

PROVABGS: The Probabilistic Stellar Mass Function of the BGS One-Percent Survey

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 […]

The DESI One-Percent Survey: Exploring the Halo Occupation Distribution of Luminous Red Galaxies and Quasi-Stellar Objects with AbacusSummit

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 […]

The need for focused, hard X-ray investigations of the Sun

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 […]

Spectral variability of photospheric radiation due to faculae II: Facular contrasts for cool main-sequence stars

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 […]
