Correcting cosmological parameter biases for all redshift surveys induced by estimating and reweighting redshift distributions
Markus Michael Rau, Ben Hoyle, Kerstin Paech +1
Photometric redshift uncertainties are a major source of systematic error for ongoing and future photometric surveys. We study different sources of redshift error caused by choosin…
Precise strong lensing mass profile of the CLASH galaxy cluster MACS 2129
A. Monna, S. Seitz, I. Balestra +12
We present a detailed strong lensing (SL) mass reconstruction of the core of the galaxy cluster MACSJ 2129.4-0741 () obtained by combining high-resolution HST pho…
The evolution of metallicity and metallicity gradients from z=2.7-0.6 with KMOS3D
Eva Wuyts, Emily Wisnioski, Matteo Fossati +28
We present measurements of the [NII]/Ha ratio as a probe of gas-phase oxygen abundance for a sample of 419 star-forming galaxies at z=0.6-2.7 from the KMOS3D near-IR multi-IFU surv…
KMOS^3D: Dynamical constraints on the mass budget in early star-forming disks
S. Wuyts, N. M. Förster Schreiber, E. Wisnioski +26
We exploit deep integral-field spectroscopic observations with KMOS/VLT of 240 star-forming disks at 0.6 < z < 2.6 to dynamically constrain their mass budget. Our sample consists o…
Stacking for machine learning redshifts applied to SDSS galaxies
Roman Zitlau, Ben Hoyle, Kerstin Paech +3
We present an analysis of a general machine learning technique called 'stacking' for the estimation of photometric redshifts. Stacking techniques can feed the photometric redshift…
Comparing Dark Energy Survey and HST-CLASH observations of the galaxy cluster RXC J2248.7-4431: implications for stellar mass versus dark matter
A. Palmese, O. Lahav, M. Banerji +65
We derive the stellar mass fraction in the galaxy cluster RXC J2248.7-4431 observed with the Dark Energy Survey (DES) during the Science Verification period. We compare the stellar…
