Measuring the Hubble constant with strongly lensed gravitational waves from space-based detector networks
Yong Yuan, Minghui Du, Wen-Fan Feng +4
The measurement of the Hubble constant plays a central role in modern cosmology. In this work, we investigate the potential of strongly lensed gravitational-wave (SLGW) signa…
An Opacity-Free Test of the Cosmic Distance Duality Relation Using Strongly Lensed Gravitational Wave Signals with Space-Based Detector Networks
Yong Yuan, Minghui Du, Benyang Zhu +4
The cosmic distance duality relation (CDDR), expressed as , is a fundamental relation in modern cosmology. In this work, we apply a method to test the CDDR…
Revisiting the Geminga halo at GeV energies with Fermi-LAT data
Yu Meng, Yun-Feng Liang, Ben-Yang Zhu +2
Nearby pulsars within are considered to be possible sources of 10-500 GeV cosmic-ray positron excess measured by PAMELA and AMS-02. A TeV halo around Geminga is…
Constraints on dark matter annihilation from a nearby subhalo candidate
Ben-Yang Zhu, Yun-Feng Liang, Xiaoyuan Huang
A recent analysis of pulsar timing data has reported evidence for a massive () dark matter subhalo located only kpc from Earth. This candid…
Constraining the parameters of heavy dark matter and memory-burdened primordial black holes with DAMPE electron measurements
Tian-Ci Liu, Ben-Yang Zhu, Yun-Feng Liang +2
The DArk Matter Particle Explorer (DAMPE) is a space-based instrument for detecting GeV-TeV cosmic rays and gamma rays. High-energy cosmic rays could be emitted from several dark m…
A neutrino flare candidate potentially associated with X-ray emission from tidal disruption event ATLAS17jrp
Rong-Lan Li, Chengchao Yuan, Hao-Ning He +5
Tidal disruption events (TDEs), in which stars are disrupted by supermassive black holes, have been proposed as potential sources of high-energy neutrinos through hadronic interact…
Constraints on primordial black holes in dSphs using radio observations
Tian-Ci Liu, Xiao-Song Hu, Yun-Feng Liang +3
Primordial black holes (PBHs) are hypothetical objects formed at the early epoch of the universe, which could be a type of dark matter (DM) candidate without the need for new parti…
Dark matter search in dwarf irregular galaxies with ten years of data from the IceCube neutrino observatory
Yi-Fei Lü, Ben-Yang Zhu, Rong-Lan Li +4
Dwarf irregular galaxies (dIrrs), as rotationally-supported systems, have more reliable J-factor measurements than dwarf spheroidal galaxies and have received attention as targets…
Constraints on the annihilation of heavy dark matter in dwarf spheroidal galaxies with gamma-ray observations
Xiao-Song Hu, Ben-Yang Zhu, Tian-Ci Liu +1
Electrons and positrons produced in dark matter annihilation can generate secondary emission through synchrotron and IC processes, and such secondary emission provides a possible m…
Searching for dark-matter induced neutrino signals in dwarf spheroidal galaxies using 10 years of IceCube public data
Xue-Kang Guo, Yi-Fei Lü, Yong-Bo Huang +3
This study searches for neutrino signals from 18 dwarf spheroidal galaxies (dSphs) using 10 years of publicly available muon-track data of the IceCube neutrino observatory. We appl…
The prediction of using LHAASO's cosmic-ray electron measurements to constrain decaying heavy dark matter
Ben-Yang Zhu, Yun-Feng Liang
LHAASO is an instrument designed for detecting cosmic rays (CRs) and gamma rays at TeV to PeV energies. The decays of heavy dark matter particles in the Galactic halo may produce h…
Investigating the correlations between IceCube high-energy neutrinos and Fermi-LAT gamma-ray observations
Rong-Lan Li, Ben-Yang Zhu, Yun-Feng Liang
We use 10 years of publicly available IceCube data to investigate the correlations between high-energy neutrinos and various Fermi-LAT gamma-ray samples. This work considers the fo…
Constraints on ultracompact minihalos from the extragalactic gamma-ray background observation
Xing-Fu Zhang, Ji-Gui Cheng, Ben-Yang Zhu +3
Ultracompact minihalo (UCMH) is a special type of dark matter halo with a very steep density profile which may form in the early universe seeded by an overdense region or a primord…
