Kavli Affiliate: Anthony Challinor | First 5 Authors: Zucheng Gao, Zvonimir Vlah, Anthony Challinor, , | Summary: We revisit the flat-sky approximation for evaluating the angular power spectra of projected random fields by retaining information about the correlations along the line of sight. With broad, overlapping radial window functions, these line-of-sight correlations are suppressed and […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Francisco Rodríguez Montero, Sergio Martin-Alvarez, Adrianne Slyz, Julien Devriendt, Yohan Dubois | Summary: During the last decade, cosmological simulations have managed to reproduce realistic and morphologically diverse galaxies, spanning the Hubble sequence. Central to this success was a phenomenological calibration of the few included feedback processes, whilst […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Lester Sandles, Francesco D’Eugenio, Jakob M. Helton, Roberto Maiolino, Kevin Hainline | Summary: We report the discovery of a quiescent galaxy at $z=2.34$ with a stellar mass of only $M_star = 9.5^{+1.8}_{-1.2} times 10^{8} mathrm{M}_odot$, based on deep JWST/NIRSpec spectroscopy. This is the least massive quiescent galaxy […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michael W. Topping, Daniel P. Stark, Ryan Endsley, Lily Whitler, Kevin Hainline | Summary: The power-law slope of the rest-UV continuum ($f_{lambda}proptolambda^{beta}$) is a key metric of early star forming galaxies, providing one of our only windows into the stellar populations and physical conditions of $z>10$ galaxies. […]
Kavli Affiliate: Kaisey Mandel | First 5 Authors: Rebekah Hounsell, Dan Scolnic, Dillon Brout, Benjamin Rose, Ori Fox | Summary: We motivate the cosmological science case of measuring Type Ia supernovae with the Nancy Grace Roman Space Telescope as part of the High Latitude Time Domain Survey. We discuss previously stated requirements for the science, […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Stefano Carniani, Giacomo Venturi, Eleonora Parlanti, Anna de Graaff, Roberto Maiolino | Summary: We investigate the incidence and properties of ionized gas outflows in a sample of 52 galaxies with stellar mass between $10^7$ M$_{odot}$ and $10^9$ M$_{odot}$ observed with ultra-deep JWST/NIRSpec MSA spectroscopy as part of […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Rosie Y. Talbot, Debora Sijacki, Martin A. Bourne, , | Summary: In this work, we use hydrodynamical simulations to explore the effects of kinetic AGN jet feedback on the progression and outcome of the major merger of two isolated, gas-rich galaxies. We present simulations that use the […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ryan Endsley, Daniel P. Stark, Lily Whitler, Michael W. Topping, Benjamin D. Johnson | Summary: Reionization is thought to be driven by faint star-forming galaxies, but characterizing this population has long remained very challenging. Here we utilize deep nine-band NIRCam imaging from JADES to study the star-forming […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Renske Smit, Aayush Saxena, Gareth C. Jones, Jakob M. Helton | Summary: We present a study of the environments of 17 Lyman-$alpha$ (Ly$alpha$) emitting galaxies (LAEs) in the reionisation era ($5.8 < z < 8$) identified by JWST/NIRSpec as part of the JWST Advanced Deep […]
