  We present the searches conducted with the Zwicky Transient Facility (ZTF) in response to S250206dm, a bona fide event with an online false alarm rate of one in 25 yr, detected by the International Gravitational Wave ...
• Anomalous narrow line Seyfert I galaxies from SDSS DR17 

  Tiwari, Arihant; Rachana; Vivek, M; Rakshit, S (American Astronomical Society, 2026-03-01)

  We present an analysis of 22,656 narrow-line Seyfert 1 galaxies (NLSy1s) from the Sloan Digital Sky Survey (SDSS) DR17 (0.1 ≤ z ≤ 0.9), identifying a sample of spectroscopically anomalous sources. These anomalies were ...
