A WFC3 Grism Emission Line Redshift Catalog in the GOODS-South Field
Aaron M. Morris, Dale D. Kocevski, Jonathan R. Trump +19
We combine HST/WFC3 imaging and G141 grism observations from the CANDELS and 3D-HST surveys to produce a catalog of grism spectroscopic redshifts for galaxies in the CANDELS/GOODS-…
XZ: Deriving redshifts from X-ray spectra of obscured AGN
Charlotte Simmonds, Johannes Buchner, Mara Salvato +2
Context: Redshifts are fundamental for our understanding of extragalactic X-ray sources. Ambiguous counterpart associations, expensive optical spectroscopy and/or multimission mult…
SCUBA-2 Ultra Deep Imaging Eao Survey (Studies) III: Multi-wavelength properties, luminosity functions and preliminary source catalog of 450-m-selected galaxies
Chen-Fatt Lim, Wei-Hao Wang, Ian Smail +35
We construct a SCUBA-2 450-m map in the COSMOS field that covers an area of 300 arcmin and reaches a 1 noise level of 0.65 mJy in the deepest region. We extract 256 s…
Compton thick active galactic nuclei in Chandra surveys
Murray Brightman, Kirpal Nandra, Mara Salvato +2
We present the results from an X-ray spectral analysis of active galactic nuclei (AGN) in the Chandra Deep Field-South, AEGIS-XD and Chandra-COSMOS surveys, focussing on the identi…
Near-Infrared Survey and Photometric Redshifts in the Extended GOODS-North field
Li-Ting Hsu, Lihwai Lin, Mark Dickinson +22
We present deep and -band images in the extended Great Observatories Origins Deep Survey-North (GOODS-N) field covering an area of 0.22 . The observations were…
A machine learning approach for identifying the counterparts of submillimetre galaxies and applications to the GOODS-North field
Ruihan Henry Liu, Ryley Hill, Douglas Scott +7
Identifying the counterparts of submillimetre (submm) galaxies (SMGs) in multiwavelength images is a critical step towards building accurate models of the evolution of strongly sta…
Investigating evidence for different black hole accretion modes since redshift z~1
A. Georgakakis, P. G. Pérez-González, N. Fanidakis +11
Chandra data in the COSMOS, AEGIS-XD and 4Ms CDFS are combined with optical/near-IR photometry to determine the rest-frame U-V vs V-J colours of X-ray AGN hosts at mean redshifts 0…
Obscuration-dependent evolution of Active Galactic Nuclei
Johannes Buchner, Antonis Georgakakis, Kirpal Nandra +9
We aim to constrain the evolution of AGN as a function of obscuration using an X-ray selected sample of AGN from a multi-tiered survey including the CDFS, AEGIS-XD, COSM…
CANDELS Multi-wavelength Catalogs: Source Detection and Photometry in the GOODS-South Field
Yicheng Guo, Henry C. Ferguson, Mauro Giavalisco +33
We present a UV-to-mid infrared multi-wavelength catalog in the CANDELS/GOODS-S field, combining the newly obtained CANDELS HST/WFC3 F105W, F125W, and F160W data with existing publ…
Are Compton-Thick AGN the Missing Link Between Mergers and Black Hole Growth?
Dale D. Kocevski, Murray Brightman, Kirpal Nandra +12
We examine the host morphologies of heavily obscured active galactic nuclei (AGN) at to test whether obscured supermassive black hole growth at this epoch is preferentiall…
CANDELS/GOODS-S, CDFS, ECDFS: Photometric Redshifts For Normal and for X-Ray-Detected Galaxies
Li-Ting Hsu, Mara Salvato, Kirpal Nandra +29
We present photometric redshifts and associated probability distributions for all detected sources in the Extended Chandra Deep Field South (ECDFS). The work makes use of the most…
