JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime
E. Iani, P. Rinaldi, A. Torralba +35
We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…
X-ray stellar feedback in low-metallicity starbursts: Insights from the template starburst galaxy ESO 338-IG04 and its halo
M. Chatzis, L. M. Oskinova, S. Reyero Serantes +7
The X-ray output of low-metallicity starburst galaxies is a key component of stellar feedback, tracing the processes responsible for gas ionization and chemical enrichment. The int…
MIDIS. Near-infrared rest-frame morphology of massive galaxies at in the Hubble eXtreme Deep Field
L. Costantin, S. Gillman, L. A. Boogaard +29
Thanks to decades of observations using the Hubble Space Telescope (HST), the structure of galaxies at redshift has been widely studied in the rest-frame ultraviolet regime,…
Insight into the Starburst Nature of Galaxy GN-z11 with JWST MIRI Spectroscopy
J. Ãlvarez-Márquez, A. Crespo Gómez, L. Colina +21
This paper presents a deep MIRI/JWST medium resolution spectroscopy (MRS) covering the rest-frame optical spectrum of the GN-z11 galaxy. The [OIII]5008 and H emission lines are…
