  • Confirmation of two magnetic cataclysmic variables as polars: 1RXS J174320.1−042953 and YY Sex 
    Rawat, Nikita; Pandey, J. C; Joshi, Arti; Potter, Stephen B; Hojaev, Alisher S; De Becker, Michael; Rao, Srinivas M; Yadava, Umesh (Oxford University Press on behalf of Royal Astronomical Society, 2023-05)
    We present our analysis of new and archived observations of two candidate magnetic cataclysmic variables, namely 1RXS J174320.1−042953 and YY Sex. 1RXS J174320.1−042953 was observed in two distinctive high and low states ...
  • Observational Properties of a Bright Type lax SN 2018cni and a Faint Type Iax SN 2020kyg 
    Singh, Mridweeka; Sahu, D. K; Dastidar, Raya; Barna, Barnabas; Misra, Kuntal; Gangopadhyay, Anjasha; Howell, D. Andrew; Jha, Saurabh W.; Im, Hyobin; Taggart, Kirsty; Andrews, Jennifer; Hiramatsu, Daichi; Teja, Rishabh Singh; Pellegrino, Craig; Foley, Ryan J.; Joshi, Arti; Anupama, G. C; Bostroem, K. Azalee; Burke, Jamison; Camacho-Neves, Yssavo; Dutta, Anirban; Kwok, Lindsey A.; McCully, Curtis; Pan, Yen-Chen; Siebert, Matt; Srivastav, Shubham; Szalai, Tamás; Swift, Jonathan J.; Yang, Grace; Zhou, Henry; DiLullo, Nico; Scheer, Jackson (American Astronomical Society, 2023-08-10)
    We present the optical photometric and spectroscopic analysis of two Type Iax supernovae (SNe), 2018cni and 2020kyg. SN 2018cni is a bright Type Iax SN (MV,peak = −17.81 ± 0.21 mag), whereas SN 2020kyg (MV,peak = −14.52 ± ...
  • Optical and X-ray studies of three polars: RX J0859.1 + 0537, RX J0749.1–0549, and RX J0649.8–0737 
    Joshi, Arti; Pandey, J. C; Singh, K. P; Anupama, G. C; Singh, H. P (Oxford University Press on behalf of the Royal Astronomical Society, 2020-01)
    We present optical photometric and spectroscopic observations, and an analysis of archival X-ray data of three polars: RX J0859.1+0537, RX J0749.1–0549, and RX J0649.8–0737. Optical light curves of these three polars reveal ...
  • SWIFT J0503.7-2819: a nearly synchronous intermediate polar below the period gap? 
    Rawat, Nikita; Pandey, J. C; Joshi, Arti; Scaringi, Simone; Yadava, Umesh (Oxford University Press on behalf of Royal Astronomical Society, 2022-12)
    Based on the X-ray observations from XMM–Newton and Swift, and optical observations from Transiting Exoplanet Survey Satellite (TESS) and AAVSO, we present temporal and spectral properties of probable intermediate polar ...
  • Unravelling optical and X-ray properties of the disc-dominated intermediate polar IGR J15094-6649 
    Joshi, Arti; Rawat, Nikita; Schwope, Axel; Pandey, J. C; Scaringi, Simone; Sahu, D. K; Rao, Srinivas M; Singh, Mridweeka (Oxford University Press on behalf of Royal Astronomical Society, 2023-06)
    We present analyses of an Intermediate Polar, IGR J15094-6649, based on the archival optical data obtained from the Transiting Exoplanet Survey Satellite (TESS) and X-ray data obtained from the Suzaku, NuSTAR, and Neil ...
