The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements
Martin Raoul Robert Millon, Mathilde Jauzac, Vivien François Bonvin, Anja Von der Linden
In late 2014, four images of Supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster field. Following the images' discovery, the SN was predicted to reappear wi ...
IOP Publishing Ltd2023Constraints on the Hubble constant from supernova Refsdal's reappearance
Martin Raoul Robert Millon, Mathilde Jauzac, Vivien François Bonvin, Anja Von der Linden
The gravitationally lensed supernova Refsdal appeared in multiple images produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeared in 2014, lens models of the galaxy cluster predicted that an additional ima ...
Washington2023The BUFFALO HST Survey
Jean-Paul Richard Kneib, Pascale Jablonka, David Richard Harvey, Benjamin Yvan Alexandre Clement, Mathilde Jauzac, Huanyuan Shan, Hakim Atek, Anja Von der Linden, Matthieu Schaller, Céline Tchernin, Richard Massey, Johan Richard
The Beyond Ultra-deep Frontier Fields and Legacy Observations (BUFFALO) is a 101 orbit + 101 parallel Cycle 25 Hubble Space Telescope (HST) Treasury program taking data from 2018 to 2020. BUFFALO will expand existing coverage of the Hubble Frontier Fields ...
IOP PUBLISHING LTD2020Spectroscopic needs for imaging dark energy experiments
Jean-Paul Richard Kneib, Johan Comparat, Anja Von der Linden
Ongoing and near-future imaging-based dark energy experiments are critically dependent upon photometric redshifts (a.k.a. photo-z's): i.e., estimates of the redshifts of objects based only on flux information obtained through broad filters. Higher-quality, ...
Elsevier2015Cl 1103.7-1245 at z=0.96: the highest redshift galaxy cluster in the EDisCS survey
Pascale Jablonka, Anja Von der Linden
We present new spectroscopic observations in a field containing the highest redshift cluster of the ESO Distant Cluster Survey (EDisCS). We measure galaxy redshifts and determine the velocity dispersions of the galaxy structures located in this field. Toge ...
Edp Sciences S A2012THE ENVIRONMENTS OF STARBURST AND POST-STARBURST GALAXIES AT z=0.4-0.8
Pascale Jablonka, Anja Von der Linden
Post-starburst (E+A or k+a) spectra, characterized by their exceptionally strong Balmer lines in absorption and the lack of emission lines, belong to galaxies in which the star formation (SF) activity ended abruptly sometime during the past Gyr. We perform ...
2009THE REST-FRAME OPTICAL LUMINOSITY FUNCTION OF CLUSTER GALAXIES AT z < 0.8 AND THE ASSEMBLY OF THE CLUSTER RED SEQUENCE
Pascale Jablonka, Anja Von der Linden
We present the rest-frame optical luminosity function (LF) of red-sequence galaxies in 16 clusters at 0.4 < z < 0.8 drawn from the ESO Distant Cluster Survey (EDisCS). We compare our clusters to an analogous sample from the Sloan Digital Sky Survey (SDSS) ...
2009Evolution of the early-type galaxy fraction in clusters since z=0.8
Pascale Jablonka, Anja Von der Linden
We study the morphological content of a large sample of high-redshift clusters to determine its dependence on cluster mass and redshift. Quantitative morphologies are based on PSF-convolved, 2D bulge+disk decompositions of cluster and field galaxies on dee ...
2009Photometric redshifts and cluster tomography in the ESO Distant Cluster Survey
Pascale Jablonka, Anja Von der Linden
Context. This paper reports the results obtained on the photometric redshifts measurement and accuracy, and cluster tomography in the ESO Distant Cluster Survey (EDisCS) fields. ...
2009The relation between star formation, morphology, and local density in high-redshift clusters and groups
Pascale Jablonka, Anja Von der Linden
We investigate how the [O II] properties and the morphologies of galaxies in clusters and groups at z = 0.4-0.8 depend on projected local galaxy density, and compare with the field at similar redshifts and clusters at low z. In both nearby and distant clus ...
