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…

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…

A Minute-Cadence Deep Bulge Survey: First Data Release of DREAMS

Hongjing Yang, Weicheng Zang, Francisco Valdes +33

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…

GW231123: A Case for Binary Microlensing in a Strong Lensing Field

Xikai Shan, Huan Yang, Shude Mao

The unusual properties of GW231123, including component masses within the pair-instability mass gap ( and at 90\%…
