The evolution of obscured AGN across cosmic time -- A large quasar survey for the 2040s
Tanya Urrutia, Darshan Kakkad, Paula Sánchez-Sáez +21
We propose a large quasar demographic optical multi-object spectroscopic (MOS) survey targeting over 50 million AGN candidates up to the highest redshifts possible in the optical (…
Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
ALMA and JWST Identification of Faint Dusty Star-Forming Galaxies up to z~8
Jorge A. Zavala, Andreas L. Faisst, Manuel Aravena +44
We exploit a new sample of around 400 bright dusty galaxies from the ALMA CHAMPS Large Program, together with the rich JWST multi-band data products in the COSMOS field, to explore…
The dwarf stellar mass function in different environments and the lack of a generic missing dwarfs problem in ΛCDM
Ilin Lazar, Sugata Kaviraj, Garreth Martin +9
We combine deep photometric data in the COSMOS and XMM-LSS fields with high-resolution cosmological hydrodynamical simulations to explore two key questions: (1) how does the galaxy…
Physical properties of galaxies and the UV Luminosity Function from to in COSMOS-Web
Maximilien Franco, Caitlin M. Casey, Hollis B. Akins +37
We present measurements of the rest-frame ultraviolet luminosity function (UVLF) in three redshift bins over -14 from the JWST COSMOS-Web survey. Our samples, selected us…
Discovery of a Little Red Dot candidate at in COSMOS-Web based on MIRI-NIRCam selection
Takumi S. Tanaka, Hollis B. Akins, Yuichi Harikane +64
JWST has revealed a new high-redshift population called little red dots (LRDs). Since LRDs may be in the early phase of black hole growth, identifying them in the early universe is…
COSMOS Web: Morphological quenching and size-mass evolution of brightest group galaxies from z = 3.7
Ghassem Gozaliasl, Lilan Yang, Jeyhan Kartaltepe +47
We present a comprehensive study of the structural evolution of Brightest Group Galaxies (BGGs) from redshift to using the \textit{James Webb Space Telesc…
A PAH deficit in the starburst core of a distant spiral galaxy
Zhaoxuan Liu, John D. Silverman, Emanuele Daddi +32
We present high-resolution and spatially-matched observations with JWST and ALMA of a starburst galaxy (PACS-830) at . The NIRCam observations mainly trace the stellar ligh…
Jet-mode feedback in NGC 5972: insights from resolved MUSE, GMRT and VLA observations
Arshi Ali, Biny Sebastian, Darshan Kakkad +10
NGC 5972, a Voorwerp galaxy, features a helical-shaped extended emission-line region (EELR) with a radius > 10 kpc and a S-shaped radio structure spanning about 470 kpc. We use VLT…
A Spectroscopically Calibrated Prescription for Extracting PAH Flux from JWST MIRI Imaging
Grant P. Donnelly, Thomas S. -Y. Lai, Lee Armus +24
We introduce a prescription for estimating the flux of the 7.7 micron and 11.3 micron\ polycyclic aromatic hydrocarbon (PAH) features from broadband JWST/MIRI images. Probing PAH f…
A multi-wavelength investigation of spiral structures in galaxies with JWST
Boris S. Kalita, Si-Yue Yu, John D. Silverman +18
Recent JWST observations have revealed the prevalence of spiral structures at . Unlike in the local Universe, the origin and the consequence of spirals at this epoch remain…
