The Dark Energy Survey Year 3 and eBOSS: constraining galaxy intrinsic alignments across luminosity and colour space
S. Samuroff, R. Mandelbaum, J. Blazek +104
We present direct constraints on galaxy intrinsic alignments using the Dark Energy Survey Year 3 (DES Y3), the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) and its prec…
Offset between X-ray and optical centers in clusters of galaxies: connecting eROSITA data and simulations
R. Seppi, J. Comparat, K. Nandra +6
The characterization of the dynamical state of clusters is key to study their evolution, their selection, and use them as a cosmological probe. The offsets between different defini…
Window function convolution with deep neural network models
Davit Alkhanishvili, Cristiano Porciani, Emiliano Sefusatti
Traditional estimators of the galaxy power spectrum and bispectrum are sensitive to the survey geometry. They yield spectra that differ from the true underlying signal since they a…
Galaxy populations in the most distant SPT-SZ clusters -- II. Galaxy structural properties in massive clusters at 1.4<z<1.7
V. Strazzullo, M. Pannella, J. J. Mohr +12
We investigate structural properties of massive galaxy populations in the central regions of five very massive galaxy clusters at z~1.4-1.7 from the South Pole Telescope Sunyaev Ze…
Searching for anisotropic stochastic gravitational-wave backgrounds with constellations of space-based interferometers
Giulia Capurri, Andrea Lapi, Lumen Boco +1
Many recent works have shown that the angular resolution of ground-based detectors is too poor to characterize the anisotropies of the stochastic gravitational-wave background (SGW…
Effects of Multiphase Gas and Projection on X-ray Observables in Simulated Galaxy Clusters as Seen by eROSITA
J. ZuHone, Y. E. Bahar, V. Biffi +8
The number density of galaxy clusters as a function of mass and redshift is a sensitive function of the cosmological parameters. To use clusters for cosmological parameter studies,…
Measuring deviations from the Kerr geometry with black hole ringdown
Kallol Dey, Enrico Barausse, Soumen Basak
Black holes in General Relativity are famously characterized by two "hairs" only, the mass and the spin of the Kerr spacetime. Theories extending General Relativity, however, allow…
Comment on "Regular evaporating black holes with stable cores"
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +2
Regular black holes are generically unstable because of the classical phenomenon that goes by the name of "mass inflation" which destabilizes the inner horizon. In a recent article…
GALLIFRAY -- A geometric modeling and parameter estimation framework for black hole images using bayesian techniques
Saurabh, Sourabh Nampalliwar
Recent observations of the galactic centers of M87 and the Milky Way with the Event Horizon Telescope have ushered in a new era of black hole based tests of fundamental physics usi…
J-PLUS DR3: Galaxy-Star-Quasar classification
R. von Marttens, V. Marra, M. Quartin +20
The Javalambre Photometric Local Universe Survey (J-PLUS) is a 12-band photometric survey using the 83-cm JAST telescope. Data Release 3 includes 47.4 million sources. J-PLUS DR3 o…
The Effect of Splashback on Weak Lensing Mass Estimates of Galaxy Clusters and Groups
Yuanyuan Zhang, Susmita Adhikari, Matteo Costanzi +3
The splashback radius of a dark matter halo, which corresponds to the first apocenter radius reached by infalling matter and substructures, has been detected around galaxy clusters…
Multi-Clustering Needlet-ILC for CMB B-modes component separation
Alessandro Carones, Marina Migliaccio, Giuseppe Puglisi +4
The Cosmic Microwave Background (CMB) primordial B-modes signal is predicted to be much lower than the polarized Galactic emission (foregrounds) in any region of the sky pointing t…
Non-local contribution from small scales in galaxy-galaxy lensing: Comparison of mitigation schemes
J. Prat, G. Zacharegkas, Y. Park +112
Recent cosmological analyses with large-scale structure and weak lensing measurements, usually referred to as 32pt, had to discard a lot of signal-to-noise from small scale…
VST-GAME: Galaxy Assembly as a function of Mass and Environment with VST. Photometric assessment and density field of MACSJ0416
Nicolas Estrada, Amata Mercurio, Benedetta Vulcani +14
Observational studies have widely demonstrated that galaxy physical properties are strongly affected by the surrounding environment. On one side, gas inflows provide galaxies with…
Timing the r-Process Enrichment of the Ultra-Faint Dwarf Galaxy Reticulum II
Joshua D. Simon, Thomas M. Brown, Burçin Mutlu-Pakdil +65
The ultra-faint dwarf galaxy Reticulum II (Ret II) exhibits a unique chemical evolution history, with 72 +10/-12% of its stars strongly enhanced in r-process elements. We present d…
Varying alpha, blinding, and bias in existing measurements
Chung-Chi Lee, John K. Webb, Robert F. Carswell +3
The high resolution spectrograph ESPRESSO on the VLT allows measurements of fundamental constants at unprecedented precision and hence enables tests for spacetime variations predic…
Structural and dynamical modeling of WINGS clusters. III. The pseudo phase-space density profile
A. Biviano, G. A. Mamon
Numerical simulations indicate that cosmological halos display power-law radial profiles of pseudo phase-space density (PPSD), Q=rho/sigma^3, where rho is mass density and sigma ve…
DS+: a method for the identification of cluster substructures
Jose A. Benavides, Andrea Biviano, Mario G. Abadi
The study of cluster substructures is important for the determination of the cluster dynamical status, assembly history, and the evolution of cluster galaxies, and it allows to set…
A study of the hydrostatic mass bias dependence and evolution within The Three Hundred clusters
Giulia Gianfagna, Elena Rasia, Weiguang Cui +4
We use a set of about 300 simulated clusters from The Three Hundred Project to calculate their hydrostatic masses and evaluate the associated bias by comparing them with the true c…
The XQR-30 Metal Absorber Catalog: 778 Absorption Systems Spanning 2 < z < 6.5
Rebecca L. Davies, Emma Ryan-Weber, Valentina D'Odorico +11
Intervening metal absorption lines in the spectra of z > 6 quasars are fundamental probes of the ionization state and chemical composition of circumgalactic and intergalactic gas n…
A Sample of Dust Attenuation Laws for DES Supernova Host Galaxies
J. Duarte, S. González-Gaitán, A. Mourao +58
Type Ia supernovae (SNe Ia) are useful distance indicators in cosmology, provided their luminosity is standardized by applying empirical corrections based on light-curve properties…
Dusty winds clear JWST super-early galaxies
Fabrizio Fiore, Andrea Ferrara, Manuela Bischetti +2
The JWST discovery of a number of super-early (redshift ), blue galaxies requires these systems to be essentially dust-free in spite of their large stellar masses. A possible…
