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…
Irony at z=6.68: a bright AGN with forbidden Fe emission and multi-component Balmer absorption
Francesco D'Eugenio, Erica Nelson, Xihan Ji +11
We present the deepest medium-resolution JWST/NIRSpec spectroscopy to date of a bright Little Red Dot (LRD) AGN, Irony at z=6.68. The data reveal broad Balmer emission from H-H$…
Lord of LRDs: Insights into a "Little Red Dot" with a low-ionization spectrum at z = 0.1
Xihan Ji, Francesco D'Eugenio, Ignas Juodžbalis +14
Recent observations by the James Webb Space Telescope (JWST) have revealed a puzzling population of optically red and compact galaxies with peculiar "V"-shaped spectra at high reds…
Low dust mass and high star-formation efficiency at from deep ALMA observations
Ikki Mitsuhashi, Jorge A. Zavala, Tom J. L. C. Bakx +15
We investigate the dust mass build-up and star formation efficiency of two galaxies at , GHZ2 and GS-z14-0, by combining ALMA and JWST observations with an analytical model t…
ALMA detection of [OIII] 88um at z=12.33: Exploring the Nature and Evolution of GHZ2 as a Massive Compact Stellar System
Jorge A. Zavala, Tom Bakx, Ikki Mitsuhashi +21
We present ALMA observations on the high-redshift galaxy GHZ2 and report a successful detection of the rest-frame 88um atomic transition from doubly-ionized Oxygen at z=12.3327+/-0…
Physical properties of circumnuclear ionising clusters. III. Kinematics of gas and stars in NGC 7742
S. Zamora, A. I. Díaz, Roberto Terlevich +2
In this third paper of a series, we study the kinematics of the ionised gas and stars, calculating the dynamical masses of the circumnuclear star-forming regions in the ring of of…
