Imprints of primordial magnetic fields on intrinsic alignments of galaxies
Shohei Saga, Maresuke Shiraishi, Kazuyuki Akitsu +1
Primordial magnetic fields (PMFs) are one of the plausible candidates for the origin of the observed large-scale magnetic fields. While many proposals have been made for the genera…
Probing cosmology via the clustering of critical points
Junsup Shim, Christophe Pichon, Dmitri Pogosyan +5
Exclusion zones in the cross-correlations between critical points (peak-void, peak-wall, filament-wall, filament-void) of the density field define quasi-standard rulers that can be…
Nonlinear redshift space distortion in halo ellipticity correlations: Analytical model and N-body simulations
Teppei Okumura, Atsushi Taruya, Toshiki Kurita +1
We present an analytic model of nonlinear correlators of galaxy/halo ellipticities in redshift space. The three-dimensional ellipticity field is not affected by the redshift-space…
First constraints on non-minimally coupled Natural and Coleman-Weinberg inflation and massive neutrino self-interactions with Planck+BICEP/Keck
Nilay Bostan, Shouvik Roy Choudhury
In this work, for the first time in literature, we study the predictions of non-minimally coupled Natural and Coleman-Weinberg potentials in the plane, and an extended C…
Beyond the Ultra-deep Frontier Fields And Legacy Observations (BUFFALO): a high-resolution strong + weak-lensing view of Abell 370
Anna Niemiec, Mathilde Jauzac, Dominique Eckert +17
The HST treasury program BUFFALO provides extended wide-field imaging of the six Hubble Frontier Fields galaxy clusters. Here we present the combined strong and weak-lensing analys…
CHEX-MATE: CLUster Multi-Probes in Three Dimensions (CLUMP-3D), I. Gas Analysis Method using X-ray and Sunyaev-Zel'dovich Effect Data
Junhan Kim, Jack Sayers, Mauro Sereno +23
Galaxy clusters are the products of structure formation through myriad physical processes that affect their growth and evolution throughout cosmic history. As a result, the matter…
A gravitational constant transition within cepheids as supernovae calibrators can solve the Hubble tension
Ruchika, Himansh Rathore, Shouvik Roy Choudhury +1
Local universe measurements of the Hubble constant (H0) using SNe Ia with Cepheids as calibrators yield a value of H0 which is in tension with the value inferred from the CMB and o…
Quadratic shape biases in three-dimensional halo intrinsic alignments
Kazuyuki Akitsu, Yin Li, Teppei Okumura
Understanding the nonlinear relation between the shapes of halos or galaxies and the surrounding matter distribution is essential in accurate modeling of their intrinsic alignments…
Cluster-counterpart Voids: Void Identification from Galaxy Density Field
Junsup Shim, Changbom Park, Juhan Kim +1
We identify cosmic voids from galaxy density fields under the theory of void-cluster correspondence. We extend the previous novel void-identification method developed for the matte…
Primordial perturbations from ultra-slow-roll single-field inflation with quantum loop effects
Shu-Lin Cheng, Da-Shin Lee, Kin-Wang Ng
It is known that the single-field inflation with a transient ultra-slow-roll phase can produce a large curvature perturbation at small scales for the formation of primordial black…
Plasma lensing with magnetic field and a small correction to the Faraday rotation measurement
Xinzhong Er, Ue-Li Pen, Xiaohui Sun +1
Plasma lensing displays interesting characteristics that set it apart from gravitational lensing. The magnetised medium induces birefringence in the two polarisation modes. As the…
Hyper Suprime-Cam Year 3 Results: Cosmology from Cosmic Shear Power Spectra
Roohi Dalal, Xiangchong Li, Andrina Nicola +35
We measure weak lensing cosmic shear power spectra from the three-year galaxy shear catalog of the Hyper Suprime-Cam (HSC) Subaru Strategic Program imaging survey. The shear catalo…
Hyper Suprime-Cam Year 3 Results: Cosmology from Galaxy Clustering and Weak Lensing with HSC and SDSS using the Minimal Bias Model
Sunao Sugiyama, Hironao Miyatake, Surhud More +27
We present cosmological parameter constraints from a blind joint analysis of three two-point correlation functions measured from the Year 3 Hyper Suprime-Cam (HSC-Y3) imaging data,…
Statistical anisotropy in galaxy ellipticity correlations
Maresuke Shiraishi, Teppei Okumura, Kazuyuki Akitsu
As well as the galaxy number density and peculiar velocity, the galaxy intrinsic alignment can be used to test the cosmic isotropy. We study distinctive impacts of the isotropy bre…
Strong gravitational lensing and microlensing of supernovae
Sherry H. Suyu, Ariel Goobar, Thomas Collett +2
Strong gravitational lensing and microlensing of supernovae (SNe) are emerging as a new probe of cosmology and astrophysics in recent years. We provide an overview of this nascent…
First Constraints on Growth Rate from Redshift-Space Ellipticity Correlations of SDSS Galaxies at
Teppei Okumura, Atsushi Taruya
We report the first constraints on the growth rate of the universe, , with intrinsic alignments (IAs) of galaxies. We measure the galaxy density-intrinsic ellipticity c…
