The Pantheon Sample Analysis of Cosmological Constraints under New Models
Peifeng Peng, Nigel Metcalfe
In this paper, the cosmological parameters are determined by applying six cosmological models to fit the magnitude-redshift relation of the Pantheon Sample consisting of 1048 Type…
GAIA Cepheid parallaxes and 'Local Hole' relieve tension
Tom Shanks, Lucy Hogarth, Nigel Metcalfe
There is an \% tension between the value of Hubble's Constant, km\,sMpc, implied by the {\it Planck} microwave background power spectr…
The Pan-STARRS1 Proper-motion Survey for Young Brown Dwarfs in Nearby Star-forming Regions. I. Taurus Discoveries and a Reddening-free Classification Method for Ultracool Dwarfs
Zhoujian Zhang, Michael C. Liu, William M. J. Best +11
We are conducting a proper-motion survey for young brown dwarfs in the Taurus-Auriga molecular cloud based on the Pan-STARRS1 3 Survey. Our search uses multi-band photometry and…

William M. J. Best, Michael C. Liu, Eugene A. Magnier +13
We present the discovery of eight young M7-L2 dwarfs in the Taurus star-forming region and the Scorpius-Centaurus OB Association, serendipitously found during a wide-field search f…
Detection of Time Lags Between Quasar Continuum Emission Bands based on Pan-STARRS Light-curves
Yan-Fei Jiang, Paul J. Green, Jenny E. Greene +21
We study the time lags between the continuum emission of quasars at different wavelengths, based on more than four years of multi-band (, , , ) light-curves in the Pan-…
Hiding in Plain Sight - Recovering Clusters of Galaxies with the Strongest AGN in Their Cores
T. S. Green, A. C. Edge, H. Ebeling +8
A key challenge in understanding the feedback mechanism of AGN in Brightest Cluster Galaxies (BCGs) is the inherent rarity of catching an AGN during its strong outburst phase. This…
First lensed quasar systems from the VST-ATLAS survey: one quad, two doubles and two pairs of lensless twins
Paul L. Schechter, Nicholas D. Morgan, B. Chehade +3
We have analyzed images from the VST ATLAS survey to identify candidate gravitationally lensed quasar systems in a sample of WISE sources with W1 - W2 > 0.7. Results from followup…
A Multi-Wavelength Photometric Census of AGN and Star Formation Activity in the Brightest Cluster Galaxies of X-ray Selected Clusters
T. S. Green, A. C. Edge, J. P. Stott +8
Despite their reputation as being "red and dead", the unique environment inhabited by Brightest Cluster Galaxies (BCGs) can often lead to a self-regulated feedback cycle between ra…
Galaxy and Mass Assembly (GAMA): Projected Galaxy Clustering
D. J. Farrow, Shaun Cole, Peder Norberg +11
We measure the projected 2-point correlation function of galaxies in the 180 deg equatorial regions of the GAMA II survey, for four different redshift slices between z = 0.0 an…
The shell game: a panoramic view of Fornax
N. F. Bate, B. McMonigal, G. F. Lewis +4
We present a panoramic study of the Fornax dwarf spheroidal galaxy, using data obtained as part of the VLT Survey Telescope (VST) ATLAS Survey. The data presented here -- a subset…
The Structure and Stellar Content of the Outer Disks of Galaxies: A New View from the Pan-STARRS1 Medium Deep Survey
Z. Zheng, D. Thilker, T. Heckman +11
We present the results of an analysis of Pan-STARRS1 Medium Deep Survey multi-band (g,r,i,z,y) images of a sample of 698 low-redshift disk galaxies that span broad ranges in stella…
Optical Confirmation and Redshift Estimation of the Planck Cluster Candidates overlapping the Pan-STARRS Survey

We report results of a study of Planck Sunyaev-Zel'dovich effect (SZE) selected galaxy cluster candidates using the Panoramic Survey Telescope & Rapid Response System (Pan-STARRS)…
Sub-millimetre source identifications and the micro-Jansky source population at 8.4 GHz in the William Herschel Deep Field
I. Heywood, R. M. Bielby, M. D. Hill +4
[Abridged] Sub-mm observations of the William Herschel Deep Field using LABOCA revealed possible counterparts for 2 X-ray absorbed QSOs. The aim here is to exploit EVLA imaging at…
The VLT LBG Redshift Survey - III. The clustering and dynamics of Lyman-break galaxies at z ~ 3
R. Bielby, M. D. Hill, T. Shanks +12
We present a catalogue of 2135 galaxy redshifts from the VLT LBG Redshift Survey (VLRS), a spectroscopic survey of z ~ 3 galaxies in wide fields centred on background quasi-stellar…
