PRISMS. UNCOVER-26185, a metal-poor SFG at z=10.05 with no evidence for a X-ray-luminous AGN

J. Álvarez-Márquez, L. Colina, A. Crespo-Gomez +31

This work presents the first results of the PRImordial galaxy Survey with MIRI Spectroscopy (PRISMS), a JWST cycle 4 program (PID 8051) aimed at the characterization of a relativel…

A close look at the black hole masses and hot dusty toruses of the first quasars with MIRI-MRS

Sarah E. I. Bosman, Javier Álvarez-Márquez, Frederick B. Davies +29

The presence of supermassive black holes (SMBHs, ) at remains a puzzle. While their existence appears to require exotic formation or growth proce…

Spatially resolved H emission in B14-65666: compact starbursts, ionizing efficiency and gas kinematics in an advanced merger at the Epoch of Reionization

C. Prieto-Jiménez, J. Álvarez-Márquez, L. Colina +28

We present MIRI/JWST medium resolution spectroscopy (MRS) and imaging (MIRIM) of B14-65666, a Lyman-break and interacting galaxy at redshift =7.15. We detect the H line emiss…

Characterising the Standardisation Properties of Type Ia Supernovae in the z band with Hierarchical Bayesian Modelling

Erin E. Hayes, Suhail Dhawan, Kaisey S. Mandel +21

Type Ia supernovae (SNe Ia) are standardisable candles: their peak magnitudes can be corrected for correlations between light curve properties and their luminosities to precisely e…

Exploring over 700 massive quiescent galaxies at z = 2-7: Demographics and stellar mass functions

William M. Baker, Francesco Valentino, Claudia del P. Lagos +6

High-redshift () massive quiescent galaxies are crucial tests of early galaxy formation and evolutionary mechanisms through their cosmic number densities and stellar mass func…
