KiDS+GAMA: Intrinsic alignment model constraints for current and future weak lensing cosmology
Harry Johnston, Christos Georgiou, Benjamin Joachimi +8
We directly constrain the non-linear alignment (NLA) model of intrinsic galaxy alignments, analysing the most representative and complete flux-limited sample of spectroscopic galax…
Herschel-ATLAS: The Surprising Diversity of Dust-Selected Galaxies in the Local Submillimetre Universe
Christopher J. R. Clark, Loretta Dunne, Haley L. Gomez +19
We present the properties of the first 250 m blind sample of nearby galaxies (15 < D < 46 Mpc) containing 42 objects from the Herschel Astrophysical Terahertz Large Area Survey…
KiDS-450: Cosmological Constraints from Weak Lensing Peak Statistics-I: Inference from Analytical Prediction of High Signal-to-Noise Ratio Convergence Peaks
HuanYuan Shan, Xiangkun Liu, Hendrik Hildebrandt +19
This paper is the first of a series of papers constraining cosmological parameters with weak lensing peak statistics using of imaging data from the Kilo Degree…
KiDS-1000: cross-correlation with Planck cosmic microwave background lensing and intrinsic alignment removal with self-calibration
Ji Yao, Huanyuan Shan, Pengjie Zhang +11
Galaxy shear - cosmic microwave background (CMB) lensing convergence cross-correlations contain additional information on cosmology to auto-correlations. While being immune to cert…
Measuring Cosmic Density of Neutral Hydrogen via Stacking the DINGO-VLA Data
Qingxiang Chen, Martin Meyer, Attila Popping +13
We use the 21 cm emission line data from the DINGO-VLA project to study the atomic hydrogen gas H\,{\textsc i} of the Universe at redshifts . Results are obtained using a st…
Cosmology from large-scale structure: Constraining CDM with BOSS
Tilman Tröster, Ariel. G. Sánchez, Marika Asgari +9
We reanalyse the anisotropic galaxy clustering measurement from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that using the full shape information provides cos…
The New Galaxy Evolution Paradigm Revealed by the Herschel Surveys
Stephen Eales, Dan Smith, Nathan Bourne +22
The Herschel Space Observatory has revealed a very different galaxyscape from that shown by optical surveys which presents a challenge for galaxy-evolution models. The Herschel sur…
A Unified Catalog-level Reanalysis of Stage-III Cosmic Shear Surveys
Emily P. Longley, Chihway Chang, Christopher W. Walter +13
Cosmological parameter constraints from recent galaxy imaging surveys are reaching -level accuracy. The upcoming Legacy Survey of Space and Time (LSST) of the Vera C. Rubin…
The SAMI Galaxy Survey: Spatially Resolving the Main Sequence of Star Formation
Anne M. Medling, Luca Cortese, Scott M. Croom +42
We present the ~800 star formation rate maps for the SAMI Galaxy Survey based on Hα emission maps, corrected for dust attenuation via the Balmer decrement, that are included in th…
A Unified Photometric Redshift Calibration for Weak Lensing Surveys using the Dark Energy Spectroscopic Instrument
Johannes U. Lange, Diana Blanco, Alexie Leauthaud +61
The effective redshift distribution of galaxies is a critical component in the study of weak gravitational lensing. Here, we introduce a new method for determining fo…
Tightening weak lensing constraints on the ellipticity of galaxy-scale dark matter haloes
Tim Schrabback, Henk Hoekstra, Ludovic Van Waerbeke +19
Cosmological simulations predict that galaxies are embedded into triaxial dark matter haloes, which appear approximately elliptical in projection. Weak gravitational lensing allows…
