Measuring peculiar velocity and tomographic redshift dipole with DESI DR1 catalogs
Yi-Wen Wu, Jun-Qing Xia
The so-called ``cosmic dipole tension'' challenges the Cosmological Principle by positing a discrepancy between the Solar System's peculiar velocity inferred from the Cosmic Microw…
Constraints on Ultralight Scalar and Dark Photon Dark Matter from PPTA-DR3 and EPTA-DR2
Xiao-Song Hu, Siyuan Chen, Kuo Liu +18
The cold dark matter model successfully describes the Universe on large scales, yet faces challenges at sub-galactic scales. Ultralight dark matter (ULDM), with particle masses aro…
Revisiting observational constraints on coupled exponential quintessence with energy and momentum transfers: degeneracy with massive neutrinos
Jose Beltrán Jiménez, Kiyotomo Ichiki, Xiaolin Liu +2
We investigate the impact of massive neutrinos on cosmological models in which dark energy, described by a quintessence scalar field with an exponential potential, interacts wi…
Avoiding recollapse in an open-AdS universe via a self-tuning-like mechanism
Yupeng Zhang, Shuxun Tian, Zhengxiang Li
We study whether an open FLRW universe with a negative cosmological constant can evade the eventual recollapse characteristic of an AdS-type universe. Within a power-law realizatio…
Redshift-binned constraints on the Hubble constant under CDM, CPL, and Padé cosmography
Zhi-Yuan Mo, Kang Jiao, Tong-Jie Zhang
Motivated by recent claims of a possible redshift dependence in late-Universe determinations of the Hubble constant (H_0), we test the robustness of this behavior using multiple co…
The SRG/eROSITA all-sky survey: The morphologies of clusters of galaxies: II. The intrinsic distributions of morphological parameters
J. S. Sanders, Y. E. Bahar, E. Bulbul +11
X-ray selected surveys of clusters of galaxies have been reported to contain more regular cool core clusters compared to samples selected using the Sunyaev-Zel'dovich (SZ) effect.…
Distinguishing the nature of dark matter by mapping cosmic filaments from Lyman-alpha emission
Yizhou Liu, Liang Gao, Shihong Liao +3
The standard CDM cosmological model predicts that cosmic filaments are highly clumpy, whereas warm dark matter -- invoked to address small-scale challenges in CDM -- produces…
Time delay measurements with Broken Power Law model
Guanhua Rui, Bin Hu, Wei Du
One challenge in strong gravitational lensing cosmography is the measurement of time delays between multiple lensed images, which are essential for constraining the Hubble constant…
