A Quiet Host in an Active Planet-Forming Disk: Optical Spectroscopy of WISPIT 2
C. Swastik, M. Bestha, L. S. Sonith +11
WISPIT 2 is a young pre-main-sequence star hosting a multi-ringed transition disk and two directly imaged protoplanets, including the accreting WISPIT 2b, making it the closest kno…
Discovery of an Unbound Flyby Companion of UBC 63: In the Immediate Aftermath of a Close Encounter
Samrat Biswas, Biman J Medhi, Sergio Messina +8
We re-investigate the open cluster UBC 63 using the Gaia DR3 data and show that, rather than being a single cluster as previously classified, it is a compelling candidate for a dou…
Near Ultraviolet Transient Explorer (NUTEx): A CubeSat-Based NUV Imaging Payload for Transient Sky Surveys
Shubham Ghatul, Rekhesh Mohan, Jayant Murthy +5
The Near Ultraviolet Transient Explorer (NUTEx) is a CubeSat-based near-ultraviolet (NUV) imaging payload designed for transient sky surveys and is currently under development. Cub…
TRAO Survey of the Nearby Filamentary Molecular Clouds, the Universal Nursery of Stars (TRAO-FUNS). IV. Filaments and Dense Cores in the W40 and Serpens South Regions of Aquila
Satyajeet Moharana, Chang Won Lee, Shinyoung Kim +9
We present the results of molecular line observations toward the W40 and Serpens South regions of the Aquila molecular cloud complex, conducted as part of the TRAO-FUNS project to…
Identification of Large-Scale (>100 kpc) Radio Jets in Narrow-Line Seyfert 1 Galaxies
S. Umayal, Vaidehi S. Paliya, D. J. Saikia +3
Powerful, large-scale relativistic jets are usually associated with massive, old elliptical galaxies. This paradigm has recently been challenged by the identification of narrow-lin…
On-axis afocal telescopes as framework for Cubesat based astronomical imagers and slit-less spectrographs
Anwesh Kumar Mishra, Gourav Banerjee, Rekhesh Mohan +1
Cubesats present unique opportunities for observational astronomy in the modern era. They are useful in observing difficult-to-access wavelength regions and long-term monitoring of…
