Study of two-electron one-photon transition produced in collision of Ne6+ ions with Al target at low energies
Shashank Singh, Mumtaz Oswal, K. P. Singh +2
Two-electron one-photon transitions have been successfully observed for the Ne projectile and Al target at low energy regime. Experimental energy values of two-electron one-photon…
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…
The Super-Soft Source Phase of the recurrent nova V3890 Sgr
J. -U. Ness, A. P. Beardmore, P. Bezak +9
The 30-year recurrent symbiotic nova V3890 Sgr exploded 2019 August 28 and was observed with multiple X-ray telescopes. An XMM-Newton observation during the SSS phase captured a hi…
Spectral States of OJ 287 blazar from Multi-wavelength Observations with
K. P. Singh, P. Kushwaha, A. Sinha +3
We present {\it AstroSat} soft X-ray, near-UV (NUV), and far-UV (FUV) observations of a blazar, OJ~287, carried out in 2017, 2018, and 2020. The simultaneous observations with NuST…
The Remarkable Spin-down and Ultra-fast Outflows of the Highly-Pulsed Supersoft Source of Nova Hercules 2021
Jeremy J. Drake, Jan-Uwe Ness, Kim L. Page +12
Nova Her 2021 (V1674 Her), which erupted on 2021 June 12, reached naked-eye brightness and has been detected from radio to -rays. An extremely fast optical decline of 2 magnitud…
K-shell ionization cross sections of Cu, Zn and Ge by 3-5 MeV/U Si-ion bombardment
Shashank Singh, Mumtaz Oswal, Sunil Kumar +3
The K x-ray spectra of different targets (Cu, Zn, and Ge) induced by 3 to 5 MeV/u Si projectile ions have been measured to determine the K-shell ionization cross-section. A signifi…
