I am a Research fellow, pursuing a Ph.D. degree in Astrophysics at the Aryabhatta Research Institute of observational Sciences (ARIES). I was born in Darbhanga, the northern district of Bihar state, also known as the cultural capital of the Mithila region . I obtained my B. Sc. degree from the University of Delhi and M. Sc. degree from the Banaras Hindu University ( BHU ). Having completed my education in Bihar, Uttar Pradesh, New Delhi, and partly in Tamil Nadu, I am currently nested in the beautiful hill city known as Nainital. My Ph.D. thesis is related to the extra-galactic domain of astrophysics. I am trying to understand the dynamics of matter in the inner regions of active galaxies. This website is my personal space where one may find articles/information related to my research, sometimes aimed for general understanding. Besides astronomy, I spend my time traveling, reading books, playing with animals, writing random things and discovering new technological advances. Since childhood, I have been fascinated by travel and thus, traveling has been one of my primary hobbies. I love writing travel articles based on my experiences! I'd like to hear from people who visit my page. You can use the social media buttons in the contact section or drop me an email.
I specialized in space physics. The cumulative grade point average (CGPA) was 7.3. The final year dissertation was titled: Study of properties of CsI as a suitable photocathode for UV astronomy purposes.
I graduated with an honors in Physics. The aggregate percentage: 68.69%
Research fellow, pursuing research at this institute leading to the Ph.D degree at DDU Gorakhpur. The details of my research activities can be found in the research section.
6 month internship project as part of Visiting Student Research program (VSRP). Project titled- Estimation of Solar magnetic fields using Spectropolarimetric data obtained from Kodaikanal Tunnel telescope. Supervised by: Dr. K Nagaraju.
Dissertation titled- Study of properties of CsI as a photo cathode for UV astronomy purposes. as part of M Sc. Physics degree. Supervised by: Prof. B.K. Singh. The dissertation work was a part of this publication and it was presented at a national conference, subsequently published in the proceedings.
I am fluent in the usage of Python language for the general programming purposes. I use astropy affiliated packages like CCDPROC and PHOTUTILS for the optical data reduction procedures. I use the mcmc based code JAVELIN extensively. Besides JAVELIN, I have used ICCF, DCF, CREAM etc. for cross correlation analysis. I have been implementing Jupyter-notebooks for most of the projects as I feel the notebook-based implementation is the most transparent and easy way for codes to work. I use GitHub for keeping the codes together and as a version control system for my projects. Besides Python based packages, I have used IDL language in the past and have some experience programming with FORTRAN as well.
I use English, Hindi and Maithili as languages for communication. Maithili is my mother tongue, Hindi was learnt as I have spent almost my entire life in Hindi speaking regions of India and English has been taught as a medium of instruction ever since I went to school. As a result, English is my primary language for all formal communications. Besides there three, I can read and write Bangla/Assamese due to my fondness for the script.
I have observed using the telescopes located at ARIES, namely, the 1.04m ST, 1.3m DFOT and 3.6m DOT . Besides these telescopes, I have observed remotely using the network of Thai Robotic Telescopes (TRT) located in USA, Australia, Thailand and China. I have the experience of reducing and analysing the data obtained from these teelscopes. We are developing an aperture photometry pipeline, written purely in PYTHON. The details can be found here. . Following is a list of competitive telescope time awarded for the various proposals:
JRF awarded for 3 years by the Department of Science and Technology (DST), an arm of Ministry of Science and Technology, Govt. of India.
Entrance exam for admission to Ph.D. in Physics at premier research institutes in India.
Competitive fellowship awarded by ISRO to the final year M.Sc students for promotion of space science research in India.
My research is currently centered in the domain of extra galactic astronomy. Our group studies the properties of the most luminous objects in the known universe yet: Active Galactic Nuclei (AGN). We use a variety of techniques backed by observational data ranging from X-ray to radio wavelengths in order to understand the behaviour of matter in the close proximate regions of the Supermassive Black Holes residing at the centre of these objects. My thesis is aimed at resolving the inner (sub-parsec) regions of these objects through multi band observations and infer the structure and kinematics of matter in those locations.
Born with an innate desire to travel around the world, I consider myself lucky to be in a profession where I can travel a lot both for work and fun. At the moment, my travel diary is filled with a few places in India coupled with a visit to China but with time I aim to travel to all the 7 continents on the planet. Some recent travel blog posts are posted below.
I traveled to Kerala in October 2018 only to be left mesmerized by the beauty, culture and the cleanliness of the part of my country rightly known as the 'God's own country'. This article is my version of the experience I had in approximately a week that I spent in Kerala.
China as a place, has always fascinated me since childhood! This article is about my maiden trip to China, which resulted due to an international conference held in Guilin, Guanxi province.
Not too many people have Nagaland in their bucket list. Uncomfortable roads, poor transport system and a lot of corruption are a few factors which contribute to it. Added to it the stories of a still very active insurgency, Nagaland although an extremely beautiful hill state doesn’t manage to attract a lot of tourists. I traveled to Nagaland and of course, will definitely want to visit again!
Sometimes few random things cross my mind and get structured in the form of sometimes little, sometimes eerily long blog posts. Currently, my blog is live on medium. A few posts are avilable below.
Two books by Sanjeev Sanyal, a noted economist: 'Ocean of Churn' and 'The land of the seven rivers' offer a very different perspective on the history of ancient India, in a manner untold before. Both of the books offer a very interesting journey through the geography of India and its surrounding lands and the ocean. I present a brief review of both the book simultaneously.
A personal account of the lockdown implemented to counter spread of the ongoing COVID-19 disease.
The radio has seen a rapid change thanks to the internet broadcast. With 100,000+ channels available to listen for free, is it a watershed moment for the world of radio entertainment? In this article, I put my thoughts regarding the resurgence of radio in the internet era and how to enthrall ourselves with the exciting world of radio.
