VLBI imaging of the gravitational lens MG J0414+0534
We observed the quadruple gravitationally lensed image of MG J0414+0534 on 23 November 1997 with a global VLBI array at 8.4 GHz. We report wide-field imaging...
WeCAPP - Wendelstein Calar Alto pixellensing project I. Tracing dark and bright matter in M 31
We present WeCAPP, a long term monitoring project searching for microlensing events towards M 31. Since 1997 the bulge of M 31 was monitored in two different...
Young Galaxy Candidates in the Hubble Frontier Fields. III. MACS J0717.5+3745
In this paper we present the results of our search for and study of z≳ 6 galaxy candidates behind the third Frontier Fields (FFs) cluster, MACS J0717.5+3745...
z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. I. Overview
Using the IRAM NOrthern Extended Millimetre Array (NOEMA), we conducted a Large Programme (z-GAL) to measure redshifts for 126 bright galaxies detected in the...
μ<SUB>⋆</SUB> masses: weak-lensing calibration of the Dark Energy Survey Year 1 redMaPPer clusters using stellar masses
We present the weak-lensing mass calibration of the stellar-mass-based μ ⋆ mass proxy for redMaPPer galaxy clusters in the Dark Energy Survey Year 1. For the...
