Gravitational lensing of gravitational waves by galaxy clusters
Xikai Shan, Yi-Fan Wang, Shude Mao +2
Strongly lensed gravitational waves (GWs) are commonly searched for using population priors, including time-delay and magnification-ratio distributions, to suppress false alarms. C…
Effective description of lensed gravitational waves diffracted by stellar fields
Miguel Zumalacárregui, Xikai Shan
As natural telescopes, Gravitational lenses enable the observation of sources that would otherwise be too distant and faint. Stellar-mass objects, or microlenses, act as impurities…
A Minute-Cadence Deep Bulge Survey: First Data Release of DREAMS
Hongjing Yang, Weicheng Zang, Francisco Valdes +31
The DECam Rogue Earths and Mars Survey (DREAMS), a NOIRLab survey program, has been conducting a three-year survey covering a 5 deg area in the Galactic bulge (roughly spanning…
KMT-2025-BLG-1616Lb: First Microlensing Bound Planet From DREAMS
Hongjing Yang, Weicheng Zang, Yoon-Hyun Ryu +60
We present observations and analysis of the bound planetary microlensing event KMT-2025-BLG-1616. The planetary signal was captured by the Korea Microlensing Telescope Network (KMT…
How significant is the lensing interpretation of GW231123?
Xikai Shan, Huan Yang, Shude Mao
GW231123 is one of the most unusual gravitational-wave (GW) events, with exceptionally large inferred masses and near-extremal spins, offering an opportunity to test whether propag…
From Stars to Waves: Stochastic Inference of Microlensed Gravitational Waves
Zhaoqi Su, Xikai Shan, Zhenwei Lyu +4
When strongly lensed gravitational waves pass through the stellar field of a lensing galaxy, they acquire additional phase and amplitude modulations from gravitational microlensing…
Gravitational lensing by a spiral galaxy I: the influence from bar's structure to the flux ratio anomaly
Xikai Shan, Yunpeng Jin, Shude Mao
Gravitational lens flux ratio anomalies are a powerful probe of small-scale mass structures, often attributed to dark matter subhalos. However, baryonic components can also play a…
Spin Precession Signatures as an Indicator of Microlensing in Strongly Lensed Gravitational Waves
Xikai Shan, Huan Yang, Shude Mao +1
Microlensing by the stellar field in a strong-lensing galaxy can introduce wave-optics distortions into the waveforms of strongly lensed gravitational waves (SLGWs). If these signa…
Multi-messenger Gravitational Lensing
Graham P. Smith, Tessa Baker, Simon Birrer +38
We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the…
Residual test to search for microlensing signatures in strongly lensed gravitational wave signals
Eungwang Seo, Xikai Shan, Justin Janquart +3
When a gravitational wave signal encounters a massive object, such as a galaxy or galaxy cluster, it undergoes strong gravitational lensing, producing multiple copies of the origin…
Wave effect of gravitational waves intersected with a microlens field II: an adaptive hierarchical tree algorithm and population study
Xikai Shan, Guoliang Li, Xuechun Chen +3
The gravitational lensing wave effect generated by a microlensing field embedded in a lens galaxy is an inevitable phenomenon in strong lensed gravitational waves (SLGWs). This eff…
Microlensing bias on the detection of strong lensing gravitational wave
Xikai Shan, Xuechun Chen, Bin Hu +1
Identifying strong lensing gravitational wave (SLGW) events is of utmost importance in astrophysics as we approach the historic first detection of SLGW amidst the growing number of…
An interference-based method for the detection of strongly lensed gravitational waves
Xikai Shan, Bin Hu, Xuechun Chen +1
The strongly lensed gravitational wave (SLGW) is a promising transient phenomenon. However, the long-wave nature of gravitational waves poses a significant challenge in identificat…
Wave effect of gravitational waves intersected with a microlens field: a new algorithm and supplementary study
Xikai Shan, Guoliang Li, Xuechun Chen +2
The increase in gravitational wave (GW) events has allowed receiving strong lensing image pairs of GWs. However, the wave effect (diffraction and interference) due to the microlens…
Lensing magnification: gravitational waves from coalescing stellar-mass binary black holes
Xikai Shan, Chengliang Wei, Bin Hu
Gravitational waves (GWs) may be magnified or de-magnified due to lensing. This phenomenon will bias the distance estimation based on the matched filtering technique. Via the multi…
