Kavli Affiliate: Michael Gladders | Summary:We present direct $T_e$ chemical abundances in five strongly lensed galaxies at Cosmic Noon ($2.481 leq z leq 3.625$) using JWST/NIRSpec data from the LEGGOS survey. We measure gas-phase abundances of N, O, S, and Ar in all five galaxies, and Ne in two galaxies. Three galaxies have electron temperature […]
Kavli Affiliate: Michael Gladders | Summary:Here we present the first systematic search for shocks in six gravitationally lensed galaxies at 2.37 < z < 3.625 with JWST/NIRSpec integral field spectroscopy from the LEnsing and Galaxy Growth: Observing Substructures (LEGGOS) survey. We employ diagnostics that utilize the fluxes and kinematics of shock-sensitive rest-frame optical emission lines […]
Kavli Affiliate: Luis Ho | Summary:We present a systematic search for intermediate-mass black hole (IMBH) active galactic nuclei (AGNs) at $0.5 < z lesssim 1$ using DESI DR1 spectroscopy.We identify 98 broad-line IMBH AGNs with black hole masses $M_mathrmBH<10^6$ $M_odot$ through quantitative spectral decomposition and broad-H$β$ selection. This sample spans $M_mathrmBH=10^5.5-10^6.0$ $M_odot$ and Eddington ratios […]
Kavli Affiliate: Roberto Maiolino | Summary: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 ($A_V>$3 mag), shows hot- and cold-dust emission, and is X-ray Compton thick, with X-ray-to-bolometric ratio consistent with luminous AGN. The large $A_V$ agrees […]

Blake | Summary: Visceral leishmaniasis (VL) is a neglected tropical disease caused by the protozoan parasites Leishmania infantum (LI) and Leishmania donovani (LD). VL disproportionately affects populations that live in extreme poverty […]

Kavli Affiliate: Luis Ho | Summary:We describe ongoing efforts of high-redshift transient searches using multi-epoch NIRCam imaging (F200W+F444W) and NIRSpec MSA/PRISM spectroscopy from the NEXUS JWST multi-cycle Treasury program targeting the north ecliptic pole region. The transient search area covers $sim 61.5,rm arcmin^2$ between the reference epoch and each subsequent NEXUS-Deep epoch at a cadence […]
