Searching for Solar-Basin Axionlike-Particle Decay with XMM-Newton Blank-Sky Observations
Bo Zhang, Chi Zhang, Lei Lei +4
Axion-like particles (ALPs) bound in the solar gravitational field form the so-called ALP solar-basin. Since the two-photon decay of non-relativistic particles is approximately iso…
New measurement at Redshift = 0.12 with DESI Data Release 1
Ze-fan Wang, Lei Lei, Yi-zhong Fan
The Hubble parameter () is a function of the redshift and a reliable measurement is very important to understand the expansion history of the Universe. In this work, we perfo…
Black Holes in the Red-sequence Elliptical Galaxies at Redshifts : Not Dark Energy Source but Remnants of Little Red Dots
Lei Lei, Ze-Fan Wang, Yi-Ying Wang +2
The nature of dark energy remains one of the most profound mysteries in modern cosmology. One intriguing proposal is that black holes (BHs) could be the astrophysical source of dar…
Possible evidence for extended X-ray emission surrounding PSR B0656+14 with eROSITA
Shu Niu, Qiang Yuan, Shui-Nai Zhang +3
Extended very-high-energy -ray emission from middle-aged pulsars as revealed recently by several groundbased -ray experiments has strong implication on the transport of high-…
Can Dark Stars account for the star formation efficiency excess at very high redshifts?
Lei Lei, Yi-Ying Wang, Guan-Wen Yuan +3
The James Webb Space Telescope (JWST) has recently conducted observations of massive galaxies at high redshifts, revealing a notable anomaly in their star formation efficiency (SFE…
JWST observations constrain the time evolution of fine structure constants and dark energy - electromagnetic coupling
Ze-Fan Wang, Lei Lei, Lei Feng +1
It was hypothesized in the literature that some physical parameters may be time-evolving and the astrophysical data can serve as a probe. Recently, James Webb Space Telescope (JWST…
Could the inter-band lag of active galactic nucleus vary randomly?
Zhen-Bo Su, Zhen-Yi Cai, Jun-Xian Wang +18
The inter-band lags among the optical broad-band continua of active galactic nuclei (AGNs) have been intensively explored over the past decade. However, the nature of the lags rema…
Searching for Axion-Like Particles with X-ray Observations of Alpha Centauri
Yu-Xuan Chen, Lei Lei, Zi-Qing Xia +3
We investigate the production of axion-like particles (ALPs) in stellar cores, where they interact with electromagnetic fields and electrons, with typical masses between $\mathcal…
The Spatial Distribution of and Ice around Protostars IRAS 16253-2429 and IRAS 23385+6053
Lei Lei, Lei Feng, Yi-Zhong Fan
The origin and evolution of organic molecules represent a pivotal issue in the fields of astrobiology and astrochemistry, potentially shedding light on the origins of life. The Jam…
Digging into the ultraviolet luminosity functions of galaxies at high redshifts: galaxies evolution, reionization, and cosmological parameters
Yi-Ying Wang, Lei Lei, Shao-Peng Tang +2
Thanks to the successful performance of the James Webb Space Telescope, our understanding of the epoch of reionization of the Universe has been advanced. The ultraviolet luminosity…
Kilonova-Targeting Lightcurve Classification for Wide Field Survey Telescope
Runduo Liang, Zhengyan Liu, Lei Lei +1

Constraints Based on Non-detection of Kilonova Optical Searching
Runduo Liang, Zhengyan Liu, Lei Lei +1
Mergers of binary neutron stars are multimessenger sources of gravitational waves that have an optical luminous counterpart, commonly referred to as 'kilonova'. Inspired by the det…
Modeling the JWST high-redshift galaxies with a general formation scenario and the consistency with the CDM model
