Euclid preparation. XCI. Validation method for the detections in the Euclid Catalogue of Galaxy Clusters using external data
Euclid Collaboration, J. -B. Melin, S. A. Stanford +315
We present our methodology for identifying known clusters as counterparts to objects in the Euclid Catalogue of Galaxy Clusters (ECGC). Euclid is expected to detect a large number…
Euclid Quick Data Release (Q1). The role of cosmic connectivity in shaping galaxy clusters
Euclid Collaboration, C. Gouin, C. Laigle +337
The matter distribution around galaxy clusters is distributed over several filaments, reflecting their positions as nodes in the large-scale cosmic web. The number of filaments con…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
The SRG/eROSITA All-Sky Survey. Optical identification and properties of galaxy clusters and groups in the western galactic hemisphere
M. Kluge, J. Comparat, A. Liu +29
The first SRG/eROSITA All-Sky Survey (eRASS1) provides the largest intracluster medium-selected galaxy cluster and group catalog covering the western galactic hemisphere. Compared…
Euclid preparation: XX. The Complete Calibration of the Color-Redshift Relation survey: LBT observations and data release
Euclid Collaboration, R. Saglia, S. De Nicola +183
The Complete Calibration of the Color-Redshift Relation survey (C3R2) is a spectroscopic programme designed to empirically calibrate the galaxy color-redshift relation to the Eucli…
Euclid preparation: I. The Euclid Wide Survey
R. Scaramella, J. Amiaux, Y. Mellier +238
Euclid is an ESA mission designed to constrain the properties of dark energy and gravity via weak gravitational lensing and galaxy clustering. It will carry out a wide area imaging…
Euclid Preparation: XIV. The Complete Calibration of the Color-Redshift Relation (C3R2) Survey: Data Release 3
Euclid Collaboration, S. A. Stanford, D. Masters +183
The Complete Calibration of the Color-Redshift Relation (C3R2) survey is obtaining spectroscopic redshifts in order to map the relation between galaxy color and redshift to a depth…
Correcting correlation functions for redshift-dependent interloper contamination
Daniel J. Farrow, Ariel G. Sánchez, Robin Ciardullo +14
The construction of catalogues of a particular type of galaxy can be complicated by interlopers contaminating the sample. In spectroscopic galaxy surveys this can be due to the mis…
Depleted Galaxy Cores and Dynamical Black Hole Masses
S. P. Rusli, P. Erwin, R. P. Saglia +4
Shallow cores in bright, massive galaxies are commonly thought to be the result of scouring of stars by mergers of binary supermassive black holes. Past investigations have suggest…
The Influence of Dark Matter Halos on Dynamical Estimates of Black Hole Mass: Ten New Measurements for High-sigma Early-Type Galaxies
S. P. Rusli, J. Thomas, R. P. Saglia +7
Adaptive-Optics assisted SINFONI observations of the central regions of ten early-type galaxies are presented. Based primarily on the SINFONI kinematics, ten black hole masses occu…
Galaxy redshift surveys with sparse sampling
Chi-Ting Chiang, Philipp Wullstein, Donghui Jeong +16
Survey observations of the three-dimensional locations of galaxies are a powerful approach to measure the distribution of matter in the universe, which can be used to learn about t…
The VIRUS-P Exploration of Nearby Galaxies (VENGA): Survey Design, Data Processing, and Spectral Analysis Methods
Guillermo A. Blanc, Tim Weinzirl, Mimi Song +14
We present the survey design, data reduction, and spectral fitting pipeline for the VIRUS-P Exploration of Nearby Galaxies (VENGA). VENGA is an integral field spectroscopic survey,…
Measuring Dark Matter Profiles Non-Parametrically in Dwarf Spheroidals: An Application to Draco
John R. Jardel, Karl Gebhardt, Maximilian Fabricius +2
We introduce a novel implementation of orbit-based (or Schwarzschild) modeling that allows dark matter density profiles to be calculated non-parametrically in nearby galaxies. Our…
Molecular gas in the centre of nearby galaxies from VLT/SINFONI integral field spectroscopy - I. Morphology and mass inventory
X. Mazzalay, R. P. Saglia, Peter Erwin +7
We present the first results of an analysis of the properties of the molecular gas in the nuclear regions (r < 300 pc) of a sample of six nearby galaxies, based on new high spatial…
Kinematic Signatures of Bulges Correlate with Bulge Morphologies and Sérsic Index
Maximilian H. Fabricius, Roberto P. Saglia, David B. Fisher +3
We use the Marcario Low Resolution Spectrograph (LRS) at the Hobby-Eberly-Telescope (HET) to study the kinematics of pseudobulges and classical bulges in the nearby universe. We pr…
