A high black hole to host mass ratio in a lensed AGN in the early Universe
Lukas J. Furtak, Ivo Labbé, Adi Zitrin +34
Early JWST observations have uncovered a new population of red sources that might represent a previously overlooked phase of supermassive black hole growth (Kocevski et al. 2023; M…
CLASSY VIII: Exploring the Source of Ionization with UV ISM diagnostics in local High- Analogs
Matilde Mingozzi, Bethan L. James, Danielle A. Berg +27
In the current JWST era, rest-frame UV spectra play a crucial role in enhancing our understanding of the interstellar medium (ISM) and stellar properties of the first galaxies in t…
GN-z11 in context: possible signatures of globular cluster precursors at redshift 10
Peter Senchyna, Adele Plat, Daniel P. Stark +1
The first JWST spectroscopy of the luminous galaxy GN-z11 simultaneously both established its redshift at and revealed a rest-ultraviolet spectrum dominated by signatures…
A variable active galactic nucleus at triply-imaged by the galaxy cluster MACS J0035.4-2015
Lukas J. Furtak, Ramesh Mainali, Adi Zitrin +32
We report the discovery of a triply imaged active galactic nucleus (AGN), lensed by the galaxy cluster MACS J0035.4-2015 (). The object is detected in Hubble…
Detection of He++ ion in the star-forming ring of the Cartwheel using MUSE data and ionizing mechanisms
Y. D. Mayya, A. Plat, V. M. A. Gómez-González +3
We here report the detection of the nebular HeII4686 line in 32 HII regions in the metal-poor collisional ring galaxy Cartwheel using the Multi-Unit Spectroscopic Explorer (MUSE) d…
JWST/NIRSpec Spectroscopy of Star Forming Galaxies with CEERS: New Insight into Bright Ly Emitters in Ionized Bubbles
Mengtao Tang, Daniel P. Stark, Zuyi Chen +9
We describe new JWST/NIRSpec observations of galaxies at taken from the CEERS survey. Previous observations of this area have revealed associations of Ly emitters at…
Optical and mid-infrared line emission in nearby Seyfert galaxies
A. Feltre, C. Gruppioni, L. Marchetti +24
Line ratio diagnostics provide valuable clues on the source of ionizing radiation in galaxies with intense black hole accretion and starbursting events, such as local Seyfert or ga…
