DESI 2024 II: Sample Definitions, Characteristics, and Two-point Clustering Statistics
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present the samples of galaxies and quasars used for DESI 2024 cosmological analyses, drawn from the DESI Data Release 1 (DR1). We describe the construction of large-scale struc…
DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars
A. G. Adame, J. Aguilar, S. Ahlen +195
We present the measurements and cosmological implications of the galaxy two-point clustering using over 4.7 million unique galaxy and quasar redshifts in the range divi…
Dark Energy Survey Year 3: Blue Shear
J. McCullough, A. Amon, E. Legnani +115
Modeling the intrinsic alignment (IA) of galaxies poses a challenge to weak lensing analyses. The Dark Energy Survey is expected to be less impacted by IA when limited to blue, sta…
Simulating realistic self-interacting dark matter models including small and large-angle scattering
Cenanda Arido, Moritz S. Fischer, Mathias Garny
Dark matter (DM) self-interactions alter the matter distribution on galactic scales and alleviate tensions with observations. A feature of the self-interaction cross section is its…
Constraints on gravity from tSZE-selected SPT galaxy clusters and weak lensing mass calibration from DES and HST
S. M. L. Vogt, S. Bocquet, C. T. Davies +52
We present constraints on the gravity model using a sample of 1,005 galaxy clusters in the redshift range that have been selected through the thermal Sunyaev-Z…
The impact of baryons on the internal structure of dark matter haloes from dwarf galaxies to superclusters in the redshift range 0<z<7
Daniele Sorini, Sownak Bose, Rüdiger Pakmor +5
We investigate the redshift evolution of the concentration-mass relationship of dark matter haloes in state-of-the-art cosmological hydrodynamic simulations and their dark-matter-o…
HOLISMOKES -- XIV. Time-delay and differential dust extinction determination with lensed type II supernova color curves
J. Grupa, S. Taubenberger, S. H. Suyu +3
The Hubble tension is one of the most relevant unsolved problems in cosmology today. Strongly gravitationally lensed transient objects, such as strongly lensed supernovae, are an i…
Enhancing weak lensing redshift distribution characterization by optimizing the Dark Energy Survey Self-Organizing Map Photo-z method
A. Campos, B. Yin, S. Dodelson +111
Characterization of the redshift distribution of ensembles of galaxies is pivotal for large scale structure cosmological studies. In this work, we focus on improving the Self-Organ…
Impact of stellar population synthesis choices on forward modelling-based redshift distribution estimates
Luca Tortorelli, Jamie McCullough, Daniel Gruen
The forward modelling of galaxy surveys has recently gathered interest as one of the primary methods to achieve the required precision on the estimate of the redshift distributions…
Dynamical friction from self-interacting dark matter
Moritz S. Fischer, Laura Sagunski
Context. Merging compact objects such as binary black holes provide a promising probe for the physics of dark matter (DM). The gravitational waves emitted during inspiral potential…
Informed total-error-minimizing priors: Interpretable cosmological parameter constraints despite complex nuisance effects
Bernardita Ried Guachalla, Dylan Britt, Daniel Gruen +1
While Bayesian inference techniques are standard in cosmological analyses, it is common to interpret resulting parameter constraints with a frequentist intuition. This intuition ca…
Detecting Galaxy Groups and AGNs populating the local Universe in the eROSITA era
I. Marini, P. Popesso, G. Lamer +14
The eROSITA will deliver an unprecedented volume of X-ray survey observations, 20-30 times more sensitive than ROSAT in the soft band (0.5-2 keV) and for the first time imaging in…
Bounds on galaxy stochasticity from halo occupation distribution modeling
Dylan Britt, Daniel Gruen, Oliver Friedrich +2
The joint probability distribution of matter overdensity and galaxy counts in cells is a powerful probe of cosmology, and the extent to which variance in galaxy counts at fixed mat…
DESI 2024 III: Baryon Acoustic Oscillations from Galaxies and Quasars
DESI Collaboration, A. G. Adame, J. Aguilar +193
We present the DESI 2024 galaxy and quasar baryon acoustic oscillations (BAO) measurements using over 5.7 million unique galaxy and quasar redshifts in the range 0.1<z<2.1. Divided…
Dianoga SIDM: galaxy cluster self-interacting dark matter simulations
Antonio Ragagnin, Massimo Meneghetti, Francesco Calura +5
This work aims at assessing the impact of DM self-interactions on the properties of galaxy clusters. In particular, the goal is to study the angular dependence of the cross section…
Dark Energy Survey Year 3 results: likelihood-free, simulation-based CDM inference with neural compression of weak-lensing map statistics
N. Jeffrey, L. Whiteway, M. Gatti +88
We present simulation-based cosmological CDM inference using Dark Energy Survey Year 3 weak-lensing maps, via neural data compression of weak-lensing map summary statistics: pow…
Numerical challenges for energy conservation in N-body simulations of collapsing self-interacting dark matter halos
Moritz S. Fischer, Klaus Dolag, Hai-Bo Yu
Dark matter (DM) halos can be subject to gravothermal collapse if the DM is not collisionless, but engaged in strong self-interactions. When the scattering can efficiently transfer…
Breakdown of Hawking Evaporation opens new Mass Window for Primordial Black Holes as Dark Matter Candidate
Valentin Thoss, Andreas Burkert, Kazunori Kohri
The energy injection through Hawking evaporation has been used to put strong constraints on primordial black holes as a dark matter candidate at masses below . How…
The boundary of cosmic filaments
Wei Wang, Peng Wang, Hong Guo +12
For decades, the boundary of cosmic filaments have been a subject of debate. In this work, we determine the physically-motivated radii of filaments by constructing stacked galaxy n…
