Filament-Arm Node Systems (FANS): A new probe of the winding and chirality of the cosmic web
Pedro da Silveira Ferreira, Renyue Cen
We define Filament-Arm Node Systems (FANS), a new class of cosmic-web objects consisting of multiple filament arms connected to a common node, and use their geometry to construct a…
Testing SALT Approximations with Numerical Radiative Transfer Code. II. Thermal and Microturbulent Line Broadening
Cody Carr, Renyue Cen, Leo Michel-Dansac +2
Forward models that connect galactic winds to their predicted spectral-line profiles have proved effective for inferring wind properties in controlled settings, but important limit…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Morphological Bias: How Ellipticals and Spirals Trace the Cosmic Web Differently
Paula S. Ferreira, Carlos A. P. Bengaly, Renyue Cen
We present a data-driven measurement of galaxy bias and scale-dependent relative bias for elliptical and spiral galaxies using angular auto- and cross-power spectra from DES and DE…
Detection of persistent helium absorption in the 91bg-like type Ia Supernova 2022an
Ping Chen, Avishay Gal-Yam, Subo Dong +14
We present optical and near-infrared observations of the fast-declining Type Ia supernova (SN Ia) 2022an. The photometric and spectroscopic properties identify it as a standard 91b…
Extending Hubble into the 2030s to Resolve the Physics of LyC Escape
Cody Carr, Stephan McCandliss, Michelle Berg +6
Current observations with the James Webb Space Telescope (JWST) suggest that star-forming galaxies produce enough ionizing (LyC; nm) photons to drive cosmic reionization,…
Recovering the infall mass for Milky Way satellite galaxy Sextans
Tingting Tian, Jiang Chang, Go Ogiya +2
Understanding the formation and evolution of the Milky Way (MW) requires detailed knowledge of its satellite galaxies. In this study, we focus on the Sextans dwarf spheroidal (dSph…
