Multiwavelength Signatures of Episodic Null Point Reconnection in a Quadrupolar Magnetic Configuration and the Cause of Failed Flux Rope Eruption
Prabir K. Mitra, Bhuwan Joshi, Astrid M. Veronig +1
In this paper, we present multiwavelength observations of the triggering of a failed-eruptive M-class flare from the active region NOAA 11302, and investigate the possible reasons…
Optical and near-infrared spectroscopy of Nova V2891 Cygni: evidence for shock-induced dust formation
Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +6
We present multi-epoch optical and near-infrared observations of the highly reddened, \pion{Fe}{ii} class slow nova V2891 Cygni. The observations span 15 months since its discovery…
A comparative study of the physical properties for a representative sample of Narrow and Broad-line Seyfert galaxies
Vivek Kumar Jha, Hum Chand, Vineet Ojha +2
We present a comparative study of the physical properties of a homogeneous sample of 144 Narrow line Seyfert 1 (NLSy1) and 117 Broad-line Seyfert 1 (BLSy1) galaxies. These two samp…
Pluto's atmosphere in plateau phase since 2015 from a stellar occultation at Devasthal
Bruno Sicardy, Nagarhalli M. Ashok, Anandmayee Tej +13
A stellar occultation by Pluto was observed on 6 June 2020 with the 1.3-m and 3.6-m telescopes located at Devasthal, Nainital, India, using imaging systems in the I and H bands, re…
Remnant radio galaxy candidates of small angular sizes
Veeresh Singh, Sushant Dutta, Yogesh Wadadekar +1
Remnant radio galaxies (RRGs), characterized by the cessation of AGN activity, represent a short-lived last phase of radio galaxy's life-cycle. Hitherto, searches for RRGs, mainly…
X-ray confirmation of the intermediate polar IGR J16547-1916
A. Joshi, W. Wang, J. C. Pandey +5
Using X-ray observations from the NuSTAR and Swift satellites, we present temporal and spectral properties of an intermediate polar (IP) IGR J16547-1916. A persistent X-ray period…
