  • ALMA-QUARKS view of W49N: Multipolar episodic outflow associated with the most energetic galactic water maser 
    Jiao, Yunfan; Liu, Tie; Jiao, Wenyu; Xu, Feng-Wei; Gu, Qilao; Tang, Xindi; Mai, Xiaofeng; Luo, Qiuyi; Zhang, Siju; Goldsmith, Paul F; Lee, Chang Won; Garay, Guido; Yang, Yuhan; Gorai, Prasanta; Merello, Manuel; Garcia, Pablo; Dib, S; Hwang, Jihye; Hoque, Ariful; Juvela, Mika; Zhang, Yankun; Sanhueza, Patricio; Weng, Jixiang; Kim, Kee-Tae; Das, Swagat; Archana Soam; Baug, Tapas; Zhou, Jianjun; Bronfman, Leonardo; Yang, A.Y; Zhu, Lei (American Astronomical Society, 2026-07)
    We present a detailed investigation of a multipolar episodic molecular outflow in the ministarburst region W49N, which hosts the most luminous water maser in the Galaxy. Using high-resolution ( ∼0.″3 ) Atacama Large ...
  • Future null energy violation and minimal dark energy solutions to the Hubble tension 
    Manoharan, Manosh T (Elsevier B. V, 2026-07)
    Few phenomenological extensions of ΛCDM favour higher values of the Hubble parameter without introducing additional degrees of freedom, often at the cost of invoking phantom dynamics. We investigate ─ Phenomenological ...
  • Broad-band spectral and temporal study of OP 313 during its 2025 January very high energy flare 
    Manzoor, Aaqib; Ahanger, Sajad; Shah, Zahir; Vivek, M; Malik, Zahoor (Elsevier B.V, 2026-07)
    We present a comprehensive broadband temporal and spectral analysis of the transition blazar OP 313 using Swift and Fermi-LAT observations obtained during its recent very high energy (VHE) flaring activity. The one-day ...
  • Ultraviolet variability in radio-loud active galactic nuclei observed by UVIT onboard AstroSat 
    Reshma, M; Stalin, C. S; Mandal, A. K; Gudennavar, S. B; Benedict, Senorita; Joseph, P (Elsevier B.V., 2026-07)
    Radio-loud active galactic nuclei (AGN) are among the most luminous objects in the Universe, emitting radiation from low-energy radio waves to high energy γ-rays. They are well known to exhibit flux variations at nearly ...
  • Narrow-line Seyfert 1 galaxies in the dark energy spectroscopic instrument data release 1 
    Paliya, Vaidehi S; Rakshit, S; Dominguez, Alberto; Saikia, D. J; Stalin, C. S (American Astronomical Society, 2026-07)
    Narrow-line Seyfert 1 (NLSy1) galaxies are peculiar active galactic nuclei (AGN) known to exhibit a variety of intriguing observational features from low-frequency radio waves to high-energy γ-rays. As of now, NLSy1 catalogs ...
