XRISM Resolves the Circum-nuclear Environment of NGC 4945
Peter G. Boorman, Poshak Gandhi, Yoshihiro Ueda +31
Compton-thick Active Galactic Nuclei (AGN) represent one of the most elusive phases of massive black hole growth, yet are expected to contribute substantially to the Cosmic X-ray B…
Euclid: Disky titans -- surprisingly high star formation efficiency in two brightest group galaxies at
F. Gentile, E. Daddi, D. Elbaz +165
We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive () star-forming (SFR /…
Euclid: Early Release Observations -- The formation of peanutty dwarf galaxies in Perseus
A. U. Kapoor, R. Smith, A. J. Zuiderwijk +133
Dwarf galaxies in dense cluster environments are susceptible to tidal interactions that can alter their morphology and kinematics. Boxy isophotes are well studied in massive galaxi…
Euclid: Galaxy morphology and photometry from bulge-disc decomposition of Early Release Observations
L. Quilley, V. de Lapparent, M. Bolzonella +168
The background galaxies in Euclid ERO images of the Perseus cluster make up a remarkable sample in its combination of 0.57 deg area, 25.3 and 23.2 AB mag depth, as well as 0.1"…
Euclid: Scaled-up little red dots and other sources with v-shaped spectral energy distributions at z>4
Euclid Collaboration, A. A. Tumborang, K. I. Caputi +169
Little Red Dots (LRDs) are some the most intriguing galaxy populations recently identified at z>~4 with JWST. They constitute the most extreme class of a more abundant population o…
JWST observations of photodissociation regions. IV. Carbonaceous emission band sub-components in NGC 7023 have distinct spatial distributions
D. Van De Putte, K. D. Gordon, K. Misselt +10
We analyze JWST spectroscopy of the northwest filament of NGC7023, where the relatively soft radiation field results in a photodissociation region with an extended atomic hydrogen…
