GA-NIFS: sRMS, a new method for disentangling resolved and unresolved emission in integral field spectroscopy. Application to distant quasars

Michele Perna, Santiago Arribas, Carlota Prieto-Jiménez +27

The interpretation of AGN emission-line profiles in type1 AGN is often complicated by the dominance of bright, spatially unresolved nuclear continuum and broad-line region (BLR) em…

GA-NIFS view of LAP1: Assembly of Pop~III stellar clusters during EoR

J. Scholtz, R. Maiolino, S. Carniani +28

Lensed and Pristine 1 (LAP1) is one of the most promising candidates for the detection of so-called Pop~III stars at . In this work, we present new high-spectral-resoluti…

Gone with the wind? Potential gas inflow in the broad-line region of a QSO at traced by time-varying Balmer absorption

Xihan Ji, Dominic J. Walton, Francesco D'Eugenio +6

We report spectroscopic observations of a remarkable QSO, J115724.80-000455.56 at from the Dark Energy Spectroscopic Instrument (DESI) survey. This QSO exhibits variabili…

LATED: JWST integral field spectroscopy of a galaxy caught in chemical infancy at behind Abell 2744

Mingyu Li, Roberto Maiolino, Zheng Cai +26

When Population III (Pop III) star formation ended remains an open question. LATED-1 is an intrinsically faint () Ly emitter at revealed by VLT/MU…

LATED: Ly-anchored photometric selection of candidate metal-free and extremely metal-poor star formation from the end of reionisation to cosmic noon

Mingyu Li, Zheng Cai, Roberto Maiolino +24

Cosmological simulations allow a low-level tail of Population III (Pop III) star formation to persist to . Spectroscopic confirmation is expensive, so an efficient photometr…

A Dusty Quenching-candidate AGN host at z=5.7: massive quiescent galaxies may quench already during the dust-obscured phase

Francesco D'Eugenio, Matilde Brazzini, Roberto Maiolino +12

We present a spectro-photometric analysis of RUBIES-EGS-9809, a broad-line AGN host at z=5.7 with a Balmer break and a dominant point source. The source is dust reddened (3 m…
