Ultra-light dark matter with non-canonical kinetics reopening the mass window
Shiyun Lu, Amara Ilyas, Xiao-Han Ma +3
Fuzzy dark matter (FDM) with mass around eV is viewed as a promising paradigm in understanding the structure formation of the local universe at small scales. Recent obse…
The PAU Survey: Photometric redshift estimation in deep wide fields
D. Navarro-Gironés, E. Gaztañaga, M. Crocce +23
We present photometric redshifts (photo-) for the deep wide fields of the Physics of the Accelerating Universe Survey (PAUS), covering an area of 50 deg, for 1…
Nested solitons in two-field fuzzy dark matter
Hoang Nhan Luu, Philip Mocz, Mark Vogelsberger +4
Dark matter as scalar particles consisting of multiple species is well motivated in string theory where axion fields are ubiquitous. A two-field fuzzy dark matter (FDM) model featu…
Growth of curvature perturbations for PBH formation \& detectable GWs in non-minimal curvaton scenario revisited
Chao Chen, Anish Ghoshal, Zygmunt Lalak +2
We revisit the growth of curvature perturbations in non-minimal curvaton scenario with a non-trivial field metric where is an inflaton field, and incorporate the effect…
Rapidly growing primordial black holes as seeds of the massive high-redshift JWST Galaxies
Guan-Wen Yuan, Lei Lei, Yuan-Zhu Wang +6
A group of massive galaxies at redshifts of have been recently detected by the James Webb Space Telescope (JWST), which were unexpected to form so early within the fra…
Sudden braking and turning with a two-field potential bump: primordial black hole formation
Chengjie Fu, Chao Chen
We investigate the amplification of curvature perturbations in a two-field inflation model featuring a Gaussian potential bump. When the inflaton encounters a potential bump along…
Missing one-loop contributions in secondary gravitational waves
Chao Chen, Atsuhisa Ota, Hui-Yu Zhu +1
We find several missing one-loop-order contributions in previous considerations about secondary gravitational waves induced at nonlinear order in cosmological perturbations. We con…
JWST's PEARLS: Prime Extragalactic Areas for Reionization and Lensing Science: Project Overview and First Results
Rogier A. Windhorst, Seth H. Cohen, Rolf A. Jansen +82
We give an overview and describe the rationale, methods, and first results from NIRCam images of the JWST "Prime Extragalactic Areas for Reionization and Lensing Science" ("PEARLS"…
Toward Cosmological Standard Timers in Primordial Black Hole Binaries
Qianhang Ding
We propose that primordial black hole (PBH) binary systems can lead to standard timers in tracking the evolution of the Universe. Through gravitational waves from monochromatic PBH…
Induced gravitational waves from statistically anisotropic scalar perturbations
Chao Chen, Atsuhisa Ota
Scalar-induced gravitational waves (SIGWs) are attracting growing attention for probing extremely short-scale scalar perturbations via gravitational wave measurements. In this pape…
Cosmological Standard Timers from Unstable Primordial Relics
Yi-Fu Cai, Chao Chen, Qianhang Ding +1
In this article we study a hypothetical possibility of tracking the evolution of our Universe by introducing a series of the so-called standard timers. Any unstable primordial reli…
Axi-Higgs cosmology: Cosmic Microwave Background and cosmological tensions
Hoang Nhan Luu
Non-canonical cosmology with an uplifted Higgs vacuum expectation value (Higgs-VEV) in the early universe is believed to provide the solution for existing tensions within the CD…
Primordial black holes and stochastic gravitational wave background from inflation with a noncanonical spectator field
Rong-Gen Cai, Chao Chen, Chengjie Fu
We investigate the enhancement of the curvature perturbations in a single-field slow-roll inflation with a spectator scalar field kinetically coupled to the inflaton. The coupling…
Ultrahigh-energy Gamma Rays and Gravitational Waves from Primordial Exotic Stellar Bubbles
Yi-Fu Cai, Chao Chen, Qianhang Ding +1
We put forward a novel class of exotic celestial objects that can be produced through phase transitions occurred in the primordial Universe. These objects appear as bubbles of stel…
Detectability of Primordial Black Hole Binaries at High Redshift
Qianhang Ding
We show that the gravitational wave signals from primordial black hole (PBH) binaries at high redshift can be detected. The detectability of PBH binaries is enhanced by redshift bi…
Gravitational waves from binary black holes as probes of the structure formation history
Tomohiro Nakama
Gravitational-wave detectors on earth have detected gravitational waves from merging compact objects in the local Universe. In future we will detect gravitational waves from higher…
On the Effective Field Theory for Quasi-Single Field Inflation
Xi Tong, Yi Wang, Siyi Zhou
We study the effective field theory (EFT) description of the virtual particle effects in quasi-single field inflation, which unifies the previous results on large mass and large mi…
Massive Fields as Systematics for Single Field Inflation
Hongliang Jiang, Yi Wang
During inflation, massive fields can contribute to the power spectrum of curvature perturbation via a dimension-5 operator. This contribution can be considered as a bias for the pr…
Inflation, String Theory and Cosmology
David F. Chernoff, S. -H. Henry Tye
At its very beginning, the universe is believed to have grown exponentially in size via the mechanism of inflation. The almost scale-invariant density perturbation spectrum predict…
