Inferring More from Less: Prospector as a Photometric Redshift Engine in the Era of JWST

The Astrophysical Journal Letters, 2023
The advent of the James Webb Space Telescope (JWST) signals a new era in exploring galaxies in the high- z universe. Current and upcoming JWST imaging will potentially detect galaxies at z ∼ 20, creating a new urgency in the quest to infer accurate ...

The Hot and Energetic Universe:The evolution of galaxy groups and clusters [PDF]

, 2013
Major astrophysical questions related to the formation and evolution of structures, and more specifically of galaxy groups and clusters, will still be open in the coming decade and beyond: what is the interplay of galaxy, supermassive black hole, and ...

A Strong Stellar Age–Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching

The Astrophysical Journal Letters
Stellar metallicity gradients (∇[ Z / H ]) provide a fossil record of the assembly history of galaxies. We present an analysis of ∇[ Z / H ] for 90 nearby low-mass galaxies using Very Large Array (VLT)/MUSE integral field unit (IFU) spectroscopy ...

A deep study of the spiral galaxy W2246f

Astronomy & Astrophysics
Aims. In this era of large surveys and statistical studies of galaxies, the beauty in the details of individual galaxies is often lost. In this paper we present a deep study of the spiral galaxy W2246f with MUSE, exploring the spatially resolved stellar ...

Gut microbiota dysbiosis‐mediated gut NLRP3 inflammasome activation exacerbates corticospinal tract injury after intracerebral hemorrhage

Interdisciplinary Medicine, EarlyView.
Schematic depicting a gut‐brain pathway that exacerbates CST injury after ICH. Gut Microbiota Dysbiosis‐Mediated Gut NLRP3 Inflammasome Activation Exacerbates Corticospinal Tract Injury After Intracerebral Hemorrhage. Abstract Intracerebral hemorrhage (ICH) causes severe neurological deficits largely attributable to corticospinal tract (CST) injury ...

Ancient Relic Moderately Metal-rich Bulge Cluster Tonantzintla 2

The Astrophysical Journal Letters
The assembly history of the Galactic bulge is intimately tied to the formation of the proto–Milky Way, yet reconstructing this early phase is difficult because mergers and secular evolution have erased most of its original structure.

The oldest stars of the bulge: new information on the ancient Galaxy

, 2017
Recently the search for the oldest stars have started to focus on the Bulge region. The Galactic bulge hosts extremely old stars, with ages compatible with the ages of the oldest halo stars.

Sensorial and nutritional qualities of muscles from cross‐bred Salers heifers raised on mid‐mountain pasture

JSFA reports, EarlyView.
Abstract Background This study investigated the effects of crossbreeding, finishing system, and muscle type on carcass characteristics, intramuscular fat (IMF), image‐based IMF estimation, fatty acid composition, and meat quality in beef heifers. Charolais × Salers (C × S) and Angus × Salers (A × S) crossbred heifers were finished either on pasture or ...
