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…
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 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…
