Currently, two faculty members and ten research scholars are engaged in the theoretical investigation of many topical issues of astrophysics and cosmology. It is noteworthy that the current post-graduate syllabus of the department includes the General Relativity course (2.5 credit) as one of the elective papers. The department also offers Astrophysics and Cosmology courses (15 credit) as special papers to its 4th semester PG students. Kanak Saha (IUCAA) has been appointed as a Visiting Professor at the ICARD, Department of Physics, CBPBU, and has been delivering lectures on Astrophysics and Cosmology courses. · Suntharalingam Thirukkanesh, Ranjan Sharma, and Shyam Das (2020) Model of a static spherically symmetric anisotropic fluid distribution in paraboloidal spacetime admitting a polytropic equation of state, EPJP, 135, 629. · Shyam Das, Ranjan Sharma, Koushik Chakraborty, and Lipi Basky (2020) Anisotropic compact stellar model of embedding class-I satisfying Karmarkar's condition in Vaidya and Tikekar spheroidal geometry, GReGr, 52, 101. · Kalikkuddy Komathiraj, and Ranjan Sharma (2020) Electromagnetic and anisotropic generalization of a plethora of well-known solutions describing relativistic compact objects, Ap&SS, 365, 181. · Kalikkuddy Komathiraj, and Ranjan Sharma (2020) Exact solution for an anisotropic star admitting the MIT Bag model equation of state, J.
