Spatially resolved gas-phase metallicity at z~2-3 with JWST/NIRISS

Ayan Acharyya, Peter J. Watson, Benedetta Vulcani +24

Spatially resolved gas-phase metallicity maps are a crucial element in understanding the chemical evolution of galaxies. We present spatially resolved metallicity maps obtained fro…

The "bubbly" interstellar medium as origin for the inhomogeneous internal metallicity distributions in large disk galaxies

Benjamin Metha, Michele Trenti, Colin Norman

Resolved metallicity studies of local disk galaxies have revealed that their interstellar media (ISMs) are far from chemically homogeneous, displaying significant ( dex)…

Thermal infrared characterization of spatially unresolved resident space objects: Prospects from analytical two-component modeling

Stephen Catsamas, Sarah Caddy, Michele Trenti +5

In this work we investigate the potential of a thermal infrared (IR) space telescope to remotely characterize the component temperatures of a satellite. With the rapid increase in…

Pushing JWST to the extremes: search and scrutiny of bright galaxy candidates at z15-30

M. Castellano, A. Fontana, E. Merlin +50

We designed customized Lyman-break color selection techniques to identify galaxy candidates in the redshift ranges and . The selection was pe…

A Lyman continuum analysis for galaxies at in the Abell 2744 Cluster Field

Y. Liu, S. Mascia, L. Pentericci +17

Identifying Lyman continuum (LyC) leakers at intermediate redshifts is crucial for understanding the properties of cosmic reionizers, as the opacity of the intergalactic medium (IG…

A "Rosetta Stone" for Studies of Spatial Variation in Astrophysical Data: Power Spectra, Semivariograms, Structure Functions, and More

Benjamin Metha, Sabrina Berger

From the turbulent interstellar medium to the cosmic web, astronomers in many different fields have needed to make sense of spatial data describing our Universe. Through different…
