Identifying type II quasars at intermediate redshift with few-shot learning photometric classification
P. A. C. Cunha, A. Humphrey, J. Brinchmann +5
We aim to identify QSO2 candidates in the redshift desert using optical and infrared photometry. At this intermediate redshift range, most of the prominent optical emission lines i…
Widespread AGN feedback in a forming brightest cluster galaxy at unveiled by JWST
Aayush Saxena, Roderik A. Overzier, Montserrat Villar-Martín +16
We present rest-frame optical spectroscopy using JWST/NIRSpec IFU for the radio galaxy TN J1338-1942 at z=4.1, one of the most luminous galaxies in the early Universe with powerful…
Optimized Spectral Energy Distribution for Seyfert Galaxies
Luc Binette, Yair Krongold, Sinhue A. R. Haro-Corzo +2
The temperature predicted by photoionization models for the Narrow Line Region of Seyfert 2 galaxies is lower than the value inferred from the observed [O III] λ4363A/λ5007A line r…
Electron Energy Distributions in the Extended Gas Nebulae associated with High-z AGN: Maxwell-Boltzmann vs. kappa distributions
S. G. Morais, A. Humphrey, M. Villar Martín +2
Emission line observations together with photoionization models provide important information about the ionization mechanisms, densities, temperatures, and metallicities in AGN-ion…
Carbon-loud SDSS BOSS QSO2s at z > 2: High density gas or secondary production of Carbon?
M. Silva, A. Humphrey, P. Lagos +1
We study the ultraviolet (UV) emission-line ratios of a sample of 145 type II quasars (QSO2s) from Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic Survey, and compare…
Detection of large scale Ly absorbers at large angles to the radio axis of high-redshift radio galaxies using SOAR
M. Silva, A. Humphrey, P. Lagos +4
We present an investigation of the properties of the extended Ly halo and the large-scale \ion{H}{I} absorbing structures associated with 5 high-redshift radio galaxies at z …
The MUSE 3D view of feedback in a high-metallicity radio galaxy at z = 2.9
M. Silva, A. Humphrey, P. Lagos +8
We present a detailed study of the kinematic, chemical and excitation properties of the giant Ly emitting nebula and the giant \ion{H}{I} absorber associated with the …
Ionization and feedback in Ly halos around two radio galaxies at z2.5
S. G. Morais, A. Humphrey, M. Villar-Martín +6
We present new spectroscopic observations of two high redshift radio galaxies, TXS 0211-122 (z=2.34) and TXS 0828+193 (z=2.57), known to be associated with large Ly halos. The o…
