On the Nature of the BeWD System Nova FQ Circinus
Shatakshi Chamoli, Philip A. Charles, Judhajeet Basu +3
The classical nova FQ Cir (Schaefer et al. 2026) has recently been shown to have a Be star donor, and has been identified as a High Mass Cataclysmic Variable (HMCV), with an orbita…
Survival of the accretion disk in LMC Recurrent Nova 1968-12a: UV--X-ray case study of the 2024 eruption
Judhajeet Basu, G. C. Anupama, Jan-Uwe Ness +3
We report on UV and X-ray observations of the 2024 eruption of the recurrent nova LMCN 1968-12a, a rapidly recurring extragalactic system with a 4.3 year recurrence period an…
Challenging Classical Paradigms: Recurrent Nova M31N 2017-01e, a BeWD system in M31?
Shatakshi Chamoli, Judhajeet Basu, Sudhanshu Barway +3
M31N 2017-01e is the second-fastest recurrent nova known, with a recurrence period of 2.5 years in the Andromeda Galaxy (M31). This system exhibits a unique combination of properti…
Discovery and Detailed Study of the M31 Classical Nova AT 2023tkw: Evidence for Internal Shocks
Judhajeet Basu, Ravi Kumar, G. C. Anupama +11
We present a detailed analysis of an extragalactic slow classical nova in M31 exhibiting multiple peaks in its light curve. Spectroscopic and photometric observations were used to…
Exploring the archives: A search for novae in UVIT snapshots of M31
Judhajeet Basu, Krishnendu S., Sudhanshu Barway +2
Extensive multi-wavelength studies of novae have been carried out in our galaxy and in M31 for decades. However, UV studies of extragalactic novae are limited, especially those in…
Searching for gravitational wave optical counterparts with the Zwicky Transient Facility: summary of O4a
Tomás Ahumada, Shreya Anand, Michael W. Coughlin +49
During the first half of the fourth observing run (O4a) of the International Gravitational Wave Network (IGWN), the Zwicky Transient Facility (ZTF) conducted a systematic search fo…
Differential Rotation of the Solar Chromosphere: A Century-long Perspective from Kodaikanal Solar Observatory Ca II K Data
Dibya Kirti Mishra, Srinjana Routh, Bibhuti Kumar Jha +5
Chromospheric differential rotation is a key component in comprehending the atmospheric coupling between the chromosphere and the photosphere at different phases of the solar cycle…
Multi-wavelength observations of multiple eruptions of the recurrent nova M31N 2008-12a
Judhajeet Basu, M. Pavana, G. C. Anupama +8
We report the optical, UV, and soft X-ray observations of the eruptions of the recurrent nova M31N 2008-12a. We infer a steady decrease in the accretion rate over the y…
Far-Ultraviolet to Near-Infrared Observations of SN 2023ixf: A high energy explosion engulfed in complex circumstellar material
Rishabh Singh Teja, Avinash Singh, Judhajeet Basu +13
We present early-phase panchromatic photometric and spectroscopic coverage spanning far-ultraviolet (FUV) to the near-infrared (NIR) regime of the nearest hydrogen-rich core-collap…
Science with the Daksha High Energy Transients Mission
Varun Bhalerao, Disha Sawant, Archana Pai +72
We present the science case for the proposed Daksha high energy transients mission. Daksha will comprise of two satellites covering the entire sky from 1~keV to ~MeV. The prima…
India's first robotic eye for time domain astrophysics: the GROWTH-India telescope
Harsh Kumar, Varun Bhalerao, G. C. Anupama +35
We present the design and performance of the GROWTH-India telescope, a 0.7 m robotic telescope dedicated to time-domain astronomy. The telescope is equipped with a 4k back-illumina…
