The Infrared Glow of Galactic Outskirts: A New Window with NASIM
Elham Saremi, Ignacio Trujillo, Mohammad Akhlaghi +5
The outskirts of galaxies retain fossil records of their assembly history and are dominated by old stellar populations shaped by tidal interactions, accretion events, and environme…
Photometric redshifts for active galactic nuclei with LePHARE for the Vera C. Rubin Observatory
R. Shirley, M. Salvato, J. Cohen-Tanugi +31
Active Galactic Nuclei (AGN) play a crucial role in galaxy evolution, but they are a minority of extragalactic sources with diverse Spectral Energy Distributions (SEDs), which depe…
Hidden Monsters with SPHEREx I: A goldmine for heavily reddened quasars at cosmic noon
Matthew Stepney, Manda Banerji, Franz E. Bauer +2
Heavily reddened quasars (HRQs) are luminous, dust-obscured broad-line quasars thought to represent a short-lived phase of intense black hole growth and feedback. Previous studies…
Spectroscopic confirmation of dual and offset quasars from the Subaru HSC-SSP program
Shenli Tang, John Silverman, Xavier Prochaska +4
We present a spectroscopic follow-up program targeting closely-separated dual quasar candidates selected from imaging of SDSS quasars with the Subaru Hyper Suprime-Cam Subaru Strat…
The rest ultraviolet to infrared spectral energy distributions of heavily reddened quasars are "V-shaped" and hot-dust poor
Matthew Stepney, Manda Banerji, Shenli Tang +2
We present a rest-ultraviolet to infrared spectral energy distribution (SED) analysis of 63 heavily reddened quasars (HRQs) at redshifts z=0.7-2.7 and with dust extinctions E(B-V)=…
Euclid Quick Data Release (Q1): Euclid spectroscopy of quasars. 1. Identification and redshift determination of 3500 bright quasars
Euclid Collaboration, Y. Fu, R. Bouwens +354
The slitless spectroscopy mode of the NISP onboard Euclid has enabled efficient spectroscopy of objects within a large FoV. We present a large and homogeneous sample of bright quas…
NASIM: Revealing the low surface brightness Universe from legacy VISTA data
Elham Saremi, Ignacio Trujillo, Mohammad Akhlaghi +5
Near-infrared imaging is a powerful technique in observational astronomy, but the bright background, primarily from the Earthś atmosphere, makes the detection of faint features par…
Evidence for universal gas depletion in a sample of 41 luminous Type 1 quasars at z 2
S. J. Molyneux, M. Banerji, M. J. Temple +9
We present ALMA CO observations of the molecular gas in a sample of 41 luminous unobscured quasars at z 2 from the Sloan Digital Sky Survey. 32 targets comprise the main sam…
A Big Red Dot: Scattered light, host galaxy signatures and multi-phase gas flows in a luminous, heavily reddened quasar at cosmic noon
Matthew Stepney, Manda Banerji, Shenli Tang +5
We present a deep X-Shooter rest-frame UV to optical spectral analysis of the heavily reddened quasar, ULASJ2315+043 at z=2.566, known to reside in a major-merger host galaxy. The…
Rich and diverse molecular gas environments of closely-separated dual quasars viewed by ALMA
Shenli Tang, John D. Silverman, Zhaoxuan Liu +12
We present a study of the molecular gas in five closely-spaced ( kpc) dual quasars () at redshifts with the…
[OIII] emission in z=2 quasars with and without Broad Absorption Lines
Matthew J. Temple, Amy L. Rankine, Manda Banerji +6
Understanding the links between different phases of outflows from active galactic nuclei is a key goal in extragalactic astrophysics. Here we compare [OIII] 4960,5008 outflow s…
AGNfitter-rx: Modelling the radio-to-X-ray SEDs of AGNs
L. N. Martínez-Ramírez, G. Calistro Rivera, Elisabeta Lusso +9
We present new frontiers in the modelling of the spectral energy distributions (SED) of active galaxies by introducing the radio-to-X-ray fitting capabilities of the publicly avail…
4MOST Consortium Survey 6: Active Galactic Nuclei
A. Merloni, D. A. Alexander, M. Banerji +17
X-ray and mid-infrared emission are signposts of the accretion of matter onto the supermassive black holes that reside at the centres of most galaxies. As a major step towards unde…
The Discovery of Gas-Rich, Dusty Starbursts in Luminous Reddened Quasars at with ALMA
Manda Banerji, C. L. Carilli, G. Jones +5
We present ALMA observations of cold dust and molecular gas in four high-luminosity, heavily reddened (A mag) Type 1 quasars at with virial M$_{\rm…
Heavily reddened type 1 quasars at z > 2 I: Evidence for significant obscured black-hole growth at the highest quasar luminosities
Manda Banerji, S. Alaghband-Zadeh, Paul C. Hewett +1
We present a new population of z>2 dust-reddened, Type 1 quasars with 0.5<E(B-V)<1.5, selected using near infra-red (NIR) imaging data from the UKIDSS-LAS, ESO-VHS and WISE surveys…
Trends in Molecular Emission from Different Extragalactic Stellar Initial Mass Functions
Manda Banerji, Serena Viti, David A. Williams
Banerji et al. (2009) suggested that top-heavy stellar Initial Mass Functions (IMFs) in galaxies may arise when the interstellar physical conditions inhibit low-mass star formation…
