Looking into the faintEst WIth MUSE (LEWIS): on the nature of ultra-diffuse galaxies in the Hydra I cluster. V. Integrated stellar population properties
Goran Doll, Chiara Buttitta, Enrichetta Iodice +19
Context: This paper presents new results from the ESO Large Programme Looking into the faintEst WIth MUSE (LEWIS). The sample consists of low-surface brightness (LSB) and ultra-dif…
HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo
P. Cox, K. M. Butler, C. R. Keeton +24
We present a study of HerS-3, a dusty star-forming galaxy at zspec = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy s…
The Tremaine-Weinberg method at high redshifts
Mahmood Roshan, Asiyeh Habibi, J. Alfonso L. Aguerri +11
This paper examines the reliability of the Tremaine-Weinberg (TW) method in measuring the pattern speed of barred galaxies at high redshifts. Measuring pattern speeds at high redsh…
Departures from Standard Disk Predictions in Intensive Ground-Based Monitoring of Three AGN
Diego Gonzalez-Buitrago, Aaron J. Barth, Rick Edelson +42
We present ground-based, multi-band light curves of the AGN Mrk~509, NGC\,4151, and NGC\,4593 obtained contemporaneously with \sw\, monitoring. We measure cross-correlation lags re…
From simulations to observations. Methodology and data release of mock TNG50 galaxies at 0.3 < z < 0.7 for WEAVE-StePS
A. Ikhsanova, L. Costantin, A. Pizzella +17
The new generation of optical spectrographs (i.e., WEAVE, 4MOST, DESI, and WST) offer unprecedented opportunities for statistically studying the star formation histories of galaxie…
Estimating Masses of Supermassive Black Holes in Active Galactic Nuclei from the Halpha Emission Line
E. Dalla BontÃ, B. M. Peterson, C. J. Grier +19
The goal of this project is to construct an estimator for the masses of supermassive black holes in active galactic nuclei (AGNs) based on the broad Halpha emission line. We make u…
