A tidal disruption event in a quasar at redshift 7.19
S. Fujimoto, Q. Fei, G. B. Brammer +41
We report a long-lived nuclear transient in GNz7q, a red quasar at powered by a black hole and hosted by a compact, dusty starburst galaxy. Th…
The JWST and ALMA view of local dwarf Pox 186: Evidence of stripped binaries driving a hard radiation field and little cold molecular gas resulting in high star-formation efficiency
Nimisha Kumari, Renske Smit, Claus Leitherer +5
We present a JWST mid-infrared (MIR) view of Pox 186, one of the best local analogs of reionization-era galaxies based on its extreme properties in the ultraviolet, optical, and fa…
A dense, metal-rich absorber driven by a heavily dust-obscured galaxy: The direct evidence of CGM enrichment at
Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +23
We report the serendipitous discovery of a dense, metal-enriched circumgalactic medium (CGM) absorber at z=7.03, together with its host galaxy, identified along the sightline towar…
Spatially resolved metallicity and ionization in the merging system Gz9p3 at z=9.3
Arjan Bik, Javier Álvarez-Márquez, Alejandro Crespo Gómez +26
Studying the interstellar medium (ISM) in merging high-redshift galaxies is crucial for understanding early galaxy assembly, star formation, and black hole growth, predicted by hie…
MIDIS: Strong H+[OIII] Line Emitters at
Thomas R. Greve, Steven Gillman, Pierluigi Rinaldi +24
We present a search for strong H+[O III] emitters at in the HUDF using ultra-deep JWST/MIRI F560W imaging from the MIDIS survey. Three galaxies are identified via p…
MIDIS: The identification of deep MIRI-red sources as candidates for extreme Balmer-break and line emitting galaxies at high-z
I. Jermann, G. Brammer, S. Gillman +27
We investigate the detection and nature of 5.6~μm MIRI-red sources in the MIRI Deep Imaging Survey (MIDIS), covering 2.4~arcmin in the Hubble Ultra Deep Field. MIDIS is the dee…
Direct pathway to the Early Supermassive Black Holes: A Red Super-Eddington Quasar in a Massive Starburst Host at
Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +24
We present a panchromatic optical-mm characterization of GNz7q, a recently identified X-ray weak, rapidly growing red quasar embedded within a dusty starburst galaxy at ,…
There Is More to Outshining: 2D Dust Effects on Stellar Mass Estimates at with JWST in the JADES Field
M. Hamed, P. G. Pérez-González, M. Annunziatella +15
Dust attenuation modifies the observed spectral energy distribution (SED), leading to biases in the properties inferred from integrated SED fitting. As spatially resolved SED model…
