Low-ionization iron-rich Broad Absorption-Line Quasar SDSS J1652+2650: Physical conditions in the ejected gas from excited FeII and metastable HeI
Balashev S. A., Ledoux C., Noterdaeme P. +4
We present high-resolution VLT/UVES spectroscopy and a detailed analysis of the unique Broad Absorption-Line system towards the quasar SDSS J165252.67+265001.96. This system exhibi…
Scale invariant curvature perturbations from a spontaneously decaying scalar field
Richard Lieu, Chun-Hui Shi
The evolution of superhorizon curvature perturbations in a two-component interacting universe is considered. It is found that adiabatic modes conserve the total curvature perturbat…
Chemo-Dynamical Tagging in the Outskirts: The Origins of Stellar Substructures in the Magellanic Clouds
César Muñoz, Antonela Monachesi, David L. Nidever +12
We present the first detailed chemical analysis from APOGEE-2S observations of stars in six regions of recently discovered substructures in the outskirts of the Magellanic Clouds e…
The Hα Luminosity Function of Galaxies at z {\sim} 4.5
Victoria Bollo, Valentino González, Mauro Stefanon +5
We present the Hα luminosity function (LF) derived from a large sample of Lyman break galaxies at z {\sim} 4.5 over the GOODS-South and North fields. This study makes use of the ne…
A redshifted excess in the broad emission lines after the flare of the -ray narrow-line Seyfert 1 PKS 2004-447
W. Hon, M. Berton, E. Sani +6
PKS 2004-447 is a narrow-line Seyfert 1 (NLS1) harbouring a relativistic jet with gamma-ray emission. On 2019-10-25, the Fermi-Large Area Telescope captured a -ray flare from th…
A Model of EUV Emission from Clusters of Galaxies
Richard Lieu, Chun-Hui Shi
With tantalizing evidence of the recent e-Rosita mission, re-discovering very soft X-rays and EUV radiation from a cluster of galaxies or its environment, the question of the origi…
Proximate molecular quasar absorbers: Chemical enrichment and kinematics of the neutral gas
P. Noterdaeme, S. Balashev, R. Cuellar +7
Proximate molecular quasar absorbers (PH2) are an intriguing population of absorption systems recently uncovered through strong H2 absorption at small velocity separation from the…
The Araucaria project: High-precision orbital parallaxes and masses of binary stars. I. VLTI/GRAVITY observations of ten double-lined spectroscopic binaries
A. Gallenne, A. Mérand, P. Kervella +4
We aim to measure very precise and accurate model-independent masses and distances of detached binary stars. Precise masses at the % level are necessary to test and calibrate…
Discovery of Hydrogen Radio Recombination Lines at z=0.89 towards PKS 1830-211
Kimberly L. Emig, Neeraj Gupta, Pedro Salas +14
We report the detection of stimulated hydrogen radio recombination line (RRL) emission from ionized gas in a galaxy using 580--1670 MHz observations from the MeerKAT Absor…
PKS1413+135: OH and HI at z = 0.247 with MeerKAT
F. Combes, N. Gupta, S. Muller +13
The BL Lac PKS 1413+135 was observed by the Large Survey Project "MeerKAT Absorption Line Survey" (MALS) in the L-band, at 1139 MHz and 1293-1379 MHz, targeting the HI and OH lines…
Expectations for time-delay measurements in active galactic nuclei with the Vera Rubin Observatory
Bozena Czerny, Swayamtrupta Panda, Raj Prince +10
The Vera Rubin Observatory will provide an unprecedented set of time-dependent observations of the sky. The planned Legacy Survey of Space and Time (LSST) operating for 10 years wi…
