Cosmological Inference from Host-Selected Type Ia Supernova Samples
Syed A Uddin, Jeremy Mould, Chris Lidman +2
We compare two Type Ia supernova (SN Ia) samples that are drawn from a spectroscopically confirmed SN Ia sample: a host-selected sample in which SNe Ia are restricted to those that…
The 2-degree Field Lensing Survey: photometric redshifts from a large new training sample to r<19.5
Christian Wolf, Andrew Johnson, Maciej Bilicki +13
We present a new training set for estimating empirical photometric redshifts of galaxies, which was created as part of the 2dFLenS project. This training set is located in a 700 sq…
2dFLenS and KiDS: Determining source redshift distributions with cross-correlations
Andrew Johnson, Chris Blake, Alexandra Amon +16
We develop a statistical estimator to infer the redshift probability distribution of a photometric sample of galaxies from its angular cross-correlation in redshift bins with an ov…
A Study of Quasar Selection in the Dark Energy Survey Supernova fields
S. S. Tie, P. Martini, D. Mudd +75
We present a study of quasar selection using the DES supernova fields. We used a quasar catalog from an overlapping portion of the SDSS Stripe 82 region to quantify the completenes…
Evidence for strong evolution in galaxy environmental quenching efficiency between z = 1.6 and z = 0.9
Julie B. Nantais, Adam Muzzin, Remco F. J. van der Burg +7
We analyse the evolution of environmental quenching efficiency, the fraction of quenched cluster galaxies that would be star-forming if they were in the field, as a function of red…
The XXL survey: first results and future
M. Pierre, C. Adami, M. Birkinshaw +108
The XXL survey currently covers two 25 sq. deg. patches with XMM observations of ~10ks. We summarise the scientific results associated with the first release of the XXL data set, t…
The 2-degree Field Lensing Survey: design and clustering measurements
Chris Blake, Alexandra Amon, Michael Childress +16
We present the 2-degree Field Lensing Survey (2dFLenS), a new galaxy redshift survey performed at the Anglo-Australian Telescope. 2dFLenS is the first wide-area spectroscopic surve…
The XXL survey XV: Evidence for dry merger driven BCG growth in XXL-100-GC X-ray clusters
S. Lavoie, J. P. Willis, J. Democles +33
The growth of brightest cluster galaxies is closely related to the properties of their host cluster. We present evidence for dry mergers as the dominant source of BCG mass growth a…
Photometric classification of type Ia supernovae in the SuperNova Legacy Survey with supervised learning
A. Möller, V. Ruhlmann-Kleider, C. Leloup +6
In the era of large astronomical surveys, photometric classification of supernovae (SNe) has become an important research field due to limited spectroscopic resources for candidate…
High-redshift supernova rates measured with the gravitational telescope A1689
Tanja Petrushevska, Rahman Amanullah, Ariel Goobar +12
We present a ground-based near-infrared search for lensed supernovae behind the massive cluster Abell 1689 at z=0.18, one of the most powerful gravitational telescopes that nature…
VDES J2325-5229 a z=2.7 gravitationally lensed quasar discovered using morphology independent supervised machine learning
Fernanda Ostrovski, Richard G. McMahon, Andrew J. Connolly +56
We present the discovery and preliminary characterization of a gravitationally lensed quasar with a source redshift and image separation of lensed by a foregrou…
Stellar mass function of cluster galaxies at z 1.5: evidence for reduced quenching efficiency at high redshift
Julie B. Nantais, Remco F. J. van der Burg, Chris Lidman +7
We present the stellar mass functions (SMFs) of passive and star-forming galaxies with a limiting mass of 10 M in four spectroscopically confirmed Spitzer Adapta…
Discovery of a z=0.65 Post-Starburst BAL Quasar in the DES Supernova Fields
Dale Mudd, Paul Martini, Suk Sien Tie +55
We present the discovery of a z=0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from…
The Volumetric Rate of Superluminous Supernovae at z~1
S. Prajs, M. Sullivan, M. Smith +12
We present a measurement of the volumetric rate of superluminous supernovae (SLSNe) at z~1, measured using archival data from the first four years of the Canada-France-Hawaii Teles…
MARZ: Manual and Automatic Redshifting Software
Samuel R. Hinton, Tamara M. Davis, Chris Lidman +2
The Australian Dark Energy Survey (OzDES) is a 100-night spectroscopic survey underway on the Anglo-Australian Telescope using the fibre-fed 2-degree-field (2dF) spectrograph. We h…
The XXL Survey: VI. The 1000 brightest X-ray point sources
S. Fotopoulou, F. Pacaud, S. Paltani +36
X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). The XXL Survey spans two fields of a combined 50 $…
The Accelerated Build-up of the Red Sequence in High Redshift Galaxy Clusters
P. Cerulo, W. J. Couch, C. Lidman +6
We analyse the evolution of the red sequence in a sample of galaxy clusters at redshifts taken from the HAWK-I Cluster Survey (HCS). The comparison with the low-redshif…
