Probing galaxy assembly bias with LRG weak lensing observations
A. Niemiec, E. Jullo, A. D. Montero-Dorta +9
In Montero-Dorta et al. 2017, we show that luminous red galaxies (LRGs) from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS) at can be divided into two grou…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
Consistent lensing and clustering in a low- Universe with BOSS, DES Year 3, HSC Year 1 and KiDS-1000
A. Amon, N. C. Robertson, H. Miyatake +105
We evaluate the consistency between lensing and clustering probes of large-scale structure based on measurements of projected galaxy clustering from BOSS combined with overlapping…
LinKS: Discovering galaxy-scale strong lenses in the Kilo-Degree Survey using Convolutional Neural Networks
C. E. Petrillo, C. Tortora, G. Vernardos +17
We present a new sample of galaxy-scale strong gravitational-lens candidates, selected from 904 square degrees of Data Release 4 of the Kilo-Degree Survey (KiDS), i.e., the "Lenses…
KiDS & Euclid: Cosmological implications of a pseudo angular power spectrum analysis of KiDS-1000 cosmic shear tomography
A. Loureiro, L. Whittaker, A. Spurio Mancini +111
We present a tomographic weak lensing analysis of the Kilo Degree Survey Data Release 4 (KiDS-1000), using a new pseudo angular power spectrum estimator (pseudo-) under d…
CODEX Weak Lensing: Concentration of Galaxy Clusters at z ~ 0.5
N. Cibirka, E. S. Cypriano, F. Brimioulle +13
We present a stacked weak lensing analysis of 27 richness selected galaxy clusters at in the CODEX survey. The fields were observed in 5 bands wit…
Discovery of superstrong, fading, iron line emission and double-peaked Balmer lines of the galaxy SDSSJ0952+2143 - the light echo of a huge flare
S. Komossa, H. Zhou, T. Wang +9
We report the discovery of superstrong, fading, high-ionization iron line emission in the galaxy SDSSJ095209.56+214313.3 (SDSSJ0952+2143 hereafter), which must have been caused by…
CODEX Weak Lensing Mass Catalogue and implications on the mass-richness relation
K. Kiiveri, D. Gruen, A. Finoguenov +19
The COnstrain Dark Energy with X-ray clusters (CODEX) sample contains the largest flux limited sample of X-ray clusters at . It was selected from ROSAT data in the…
The Effects of Superhigh Magnetic Fields on Equations of States of Neutron Stars
Z. F. Gao, N. Wang, Y. Xu +2
By introducing Dirac ?-function in superhigh magnetic field, we deduce a general formula for pressure of degenerate and relativistic electrons, Pe, which is suitable for superhigh…
The effects of UV photometry and binary interactions on photometric redshift and galaxy morphology
F. Zhang, Z. Han, L. Li +2
Using the Hyperz code and a template spectral library which consists of 4 observed galaxy spectra from Coleman, Wu & Weedman (CWW, 1980) and 8 spectral families built with evolutio…
Could the low braking index pulsar PSR J1734-3333 evolve into a magnetar?
Z. -F. Gao, D. -L. Song, Y. -L. Liu +3
The low braking-index pulsar PSR J17343333 could be born with superhigh internal magnetic fields G, and undergo a supercritical accretion soon af…
Weak-Lensing Mass Calibration of the Atacama Cosmology Telescope Equatorial Sunyaev-Zeldovich Cluster Sample with the Canada-France-Hawaii Telescope Stripe 82 Survey
N. Battaglia, A. Leauthaud, H. Miyatake +39
Mass calibration uncertainty is the largest systematic effect for using clusters of galaxies to constrain cosmological parameters. We present weak lensing mass measurements from th…
