The PANE Winter School 2025 - Introductory Course on Astrophysics and Cosmology - was successfully organised by the Physics Academy of the North East from 8 to 20 December 2025. The daily schedule from 3:00 PM to 7:00 PM was designed to facilitate the participation of graduating students, enabling them to attend the sessions after regular academic hours.

The Winter School was convened by Dr. Sanjeev Kalita  of Gauhati University and was aimed at PhD scholars, MSc students, and exceptionally motivated BSc students. The course was structured to introduce the foundational concepts of Astrophysics and Cosmology essential for initiating research in these areas. The academic programme comprised a series of expert lectures covering Stellar Astrophysics, General Relativity and Black Hole Physics, and Cosmology, complemented by several interactive tutorial sessions to enhance conceptual understanding and student engagement.

The lectures were delivered by experts in these fields, including:

•Dr. Sumanta Chakraborty, IACS

•Prof. Santabrata Das, IIT Guwahati

•Dr. Anupam Bhardwaj, IUCAA

•Dr. Biman J. Medhi, Gauhati University

•Dr. Sukanta Deb, Cotton University

•Prof. Atri Deshamukhya, Assam University

•Dr. Subinoy Das, IISc

•Dr. Sanjeev Kalita, Gauhati University

The Winter School witnessed enthusiastic participation from about 100 students and researchers drawn from various parts of India, reflecting the growing interest in Astrophysics and Cosmology among young scholars.

To support effective learning, study materials and recorded lecture videos were provided to all participants at the end of each session. The programme was widely appreciated for its academic depth, clarity of presentation, and interactive format, and it contributed significantly to capacity building in frontier areas of physics in the North Eastern region and beyond.
