Scylla: Observational Evidence for an Order of Magnitude in Dust-mass Opacity Evolution with Interstellar Medium Density in the Large Magellanic Cloud

Christina W. Lindberg, Christopher Clark, Claire E. Murray, Julia Román-Duval et autres

Abstract The emissivity of dust is known to vary greatly with radiative environment, density, grain chemistry, and geometry. Discrepancies between dust-mass surface densities derived from far-infrared (FIR) emission and visible extinction persist across and within galaxies in the local Universe. Here, we …

Large Variations Seen in First Ultraviolet Spectroscopic M33 Dust Extinction Curves

Karl D. Gordon, Petia Yanchulova Merica-Jones, Geoffrey C. Clayton, R. C. Bohlin et autres

Abstract Dust extinction curves provide one of the main avenues to understanding the detailed nature of dust grains and accounting for the effects of dust on observations of many astrophysical objects. For the first time, spectroscopic ultraviolet (UV) extinction curves are measured …

Detecting gravitational lensing by matter currents

Claire E. Murray, Raphaël Kou, J. G. Bartlett

We explored the observational prospects for detecting gravitational lensing induced by cosmological matter currents, a relativistic correction to the standard density lensing effect arising from the motion of matter. We propose isolating this contribution by cross-correlating the weak-lensing convergence field with a …

The Impact of the MAST Data Archive

R.A. Shaw, Jenny Novacescu, Sarah Weissman, Travis A. Berger et autres

The Barbara A. Mikulski Archive for Space Telescopes (MAST) hosts science-ready data products from over twenty NASA missions, plus community-contributed data collections, and other select surveys. The data support forefront research in the ultraviolet, optical, and near-infrared wavelength bands. We have constructed …

Euclid Quick Data Release (Q1)

P. Bergamini, M. Meneghetti, A. Acebron, B. Clément et autres

We present the first catalogue of strong-lensing galaxy clusters identified in the Euclid Quick Release 1 observations (covering 63.1 deg 2 ). This catalogue is the result of the visual inspection of 1260 Euclid image cutouts of previously identified galaxy clusters. Each …

The Local Group L-band Survey: Probing Cold Atomic Gas in IC10 with Neutral Hydrogen Absorption

Ioana A. Stelea, Snežana Stanimirović, Nickolas M. Pingel, Hongxing Chen et autres

We present the first localized detections of the cold neutral medium (CNM) in IC10, offering a rare view of dense atomic gas in a low-metallicity (0.27 solar metallicity) dwarf galaxy. As a low-metallicity starburst, IC10's interstellar medium conditions could reflect small-scale physical …

B. Margalef-Bentabol, L. Wang, Antonio La Marca, Vicente Rodríguez-Gómez et autres

Active galactic nuclei (AGN) are an important phase in galaxy evolution. However, they can be difficult to identify due to their varied observational signatures. Furthermore, to understand the impact of an AGN on its host galaxy, it is important to quantify the …

Scylla V: Constraints on the spatial and temporal distribution of bursts and the interaction history of the Magellanic Clouds from their resolved stellar populations

Clare Burhenne, Kristen B. W. McQuinn, Roger E. Cohen, Claire E. Murray et autres

We measure the star formation histories (SFHs) from the Scylla survey in approximately 98,000 pc^2 and 75,000 pc^2 of the SMC and LMC, respectively, using deep Hubble Space Telescope imaging (80% complete to more than 1 mag below the ancient main-sequence turnoff, …

Multiwavelength probes of the Milky Way’s cold interstellar medium: radio H i and optical K i absorption with GASKAP and GALAH

Hiep Nguyen, Sven Buder, J. D. Soler, N. M. McClure‐Griffiths et autres

ABSTRACT We present a comparative analysis of interstellar hydrogen (H i) and potassium (K i) absorption from the radio and optical surveys, GASKAP (Galactic Australian Square Kilometre Array Pathfinder) and GALAH (Galactic Archaeology with HERMES), to study the physical and kinematic properties …
