Yashpal Bhulla, PrasunDhang, Ritesh Ghosh, Rukaiya Khatoon, SapnaMishra, AyanMitra, AbhishekMohapatra, Divya Rawat, andAditi Vijayan have joined as Post-doctoral fellows. Welcome to . . . | KHAG L | No. 128 - OCTOBER 2021 | 04 PrasunDhang, who has joined IUCAAinAugust 2021 as a Post-Doctoral Fellow. Earlier, he was a PDFat the Tsinghua University, Beijing, China (during September 2019 – July 2021). He has done his doctoral work at the Department of Physics, IISc, Bengaluru. He has studied different aspects of accretion physics using high-resolution hydrodynamic, magnetohydrodynamic and general relativistic magnetohydrodynamic simulations. He has specifically focused on the study of QPOs, angularmomentum transport, generation, and transport of large-scalemagnetic fields in a turbulent accretion flow. R itesh Ghosh, who has carried out his doctoral research work at the Department of Physics, Visva-Bharati University, Santiniketan, in the field of observational X-ray astronomy. For his doctoral thesis, he has studied the disk-corona and jet emission from radio-loud type 1 AGNs, and a sample of low-luminous quasars, where he has investigated the reason for their low luminosity. His present research work primarily revolves around the multi-wavelength analysis of the unresolved central region of the AGN to disentangle the disk-corona-jet emission in radio- loud AGNs, the origin of reflection features in the X-ray spectra of type 1 AGNs, tracking the evolutionary scenario of quasars, and hence, the supermassive black hole host galaxy interaction and the effect of theAGN on the kilo parsec-scale molecular outflows. He has joined IUCAAas a Post-Doctoral Fellow inAugust 2021. Abhisek Mohapatra did his M.Sc. from the Central University of Himachal Pradesh in 2015. Then, he obtained his Ph.D. degree in 2021 from NIT Rourkela. His broad field of research is observational astronomy. For the doctoral thesis, he analyzed the intervening gas in the intergalactic medium (IGM) and circum galactic medium (CGM) using absorption lines imprinted on the spectra of background quasars. He used both optical and UV data during his doctoral work. He joined IUCAAas a postdoctoral fellow to work on HI emission galaxies using the large volume of radio interferometric data obtained from the MeerKAT Absorption Line Survey (MALS). He plans to exploit the plethora of MALS data to surveyHI emission sources and then study various HI scaling relations. This survey will be a test bed for understanding the underlying statistical properties of scaling relations, which are key ingredients of galaxy formationmodels. Aditi Vijayan, whowas a student of 2015 - batch JointAstronomy Programme (JAP) at the Indian Institute of Science, Bengaluru. She has joined IUCAAas a Post-Doctoral Fellow in August 2021. She pursued PhDwork at the Raman Research Institute, Bengaluru, and her thesis focused on the role played by supernova-driven outflows in shaping the properties of gas around galaxy. She works mainly with the astrophysical code PLUTO to undertake simulations of star-forming galaxies like our own Milky Way. Previously, she was associated with Shanghai Astronomical Observatory (SHAO), China, as a Visiting Scholar, where she was studying the properties of diffuse X-ray emission emanating from the circum-galactic medium around elliptical galaxies. In her spare time, she likes reading fiction andwriting book reviews on her blog intermittently.
