Dr. Prantika Bhowmik joins IISc as an Assistant Professor

It is a matter of immense pride to us that our alumni, Dr. Prantika Bhowmik, PhD student of Prof. Dibyendu Nandi, has joined the Physics Department of the Indian Institute of Science, Bengaluru, as a faculty member.

Prantika was a first batch PhD student at the Centre of Excellence in Space Sciences, India (CESSI), joining the program in 2013. Her thesis focused on the development of computation models for forecasting the Sun\'s magnetic cycle. She received the Justice Oak Best Thesis Award from the Astronomical Society of India and the PhD at Large prize of the International Astronomical Union for her thesis work. Subsequently, she moved to the Solar Group at the Department of Mathematics at Durham University as a Postdoc. Finally, she joined IISc as an Assistant Professor this month.

Anand Dev Ranjan awarded an SPIE Optics and Photonics Scholarship

Anand Dev Ranjan has been awarded a 2024 Optics and Photonics Scholarship by SPIE, the International Society for optics and photonics, for potential contributions to optics, photonics, or a related field.

Dev Ranjan is currently working with Professor Ayan Banerjee in the Department of Physical Sciences at the Indian Institute of Science Education and Research Kolkata (India). He focuses on two significant challenges in today’s world: The growing demand for faster and more cost-effective biosensors, supplemented by a need for more congenial fabrication strategies. “My work focuses on microbubble lithography - a technique for developing microscopic patterns of diverse materials using microbubbles created by a high-intensity laser spot inside optical tweezers,” noted Dev Ranjan. “These microbubbles can cause dispersed materials to self-assemble, resulting in the formation of continuous patterns.” Dev Ranjan is harnessing this technique to develop a multi-disease diagnostic platform. “I am pursuing research with a motivation to serve both science and society,” said Dev Ranjan. “Thank you, SPIE, for appreciating my work. I am especially grateful to my family, friends, professors, and Krushna.”

This month, the Society is awarding $303,000 in scholarships to 72 outstanding SPIE Student Members, based on their potential contribution to optics and photonics, or a related discipline. Successful applicants were evaluated, selected, and approved by the SPIE Scholarship Committee, chaired by SPIE Senior Member Brian Primeau.

This book, "UNIVERSE" written in the Mizo language, is part of an astronomy outreach for the local Mizo people. The book is prepared precisely in most laymen's terms without losing the philosophy of science. This is the first-ever book recorded in Mizo literature that is mainly devoted entirely to the understanding of the universe. The book starts with an introduction to particle physics and ends with the ultimate fate of the universe. It also includes chapters separately on a timeline of astronomy, the importance of astronomy in daily life, an introduction to the general theory of relativity, the large-scale structure of the universe, exploring the solar system, the life of stars, the galactic centre, exoplanets and astronomical techniques.

Fazal Kareem, a DPS undergraduate student, is a part of the collaboration of the gravitational wave discovery.

Indian Pulsar Timing Array reports early signs of a Gravitational Wave background in our combined dataset with the European Pulsar Timing Array. These results corroborate with those from NANOGrav and Parkes Pulsar Timing Array. This background likely has its origins in merging supermassive black holes all across the universe, though the signal may have signs of other phenomena such as phase transitions in the earth universe. These experiments use radio telescopes to observe pulsars, rapidly rotating neutron stars which can be used like celestial clocks. As GWs are perturbations in space-time, these experiments detect a change in the way these clocks keep time, hence detecting gravitational waves.

Dr. H. V. Ragavendra publishes in Physical Review Letters: Observing Nulling of Primordial Correlations via the 21-cm Signal

The behavior of primordial quantum fluctuations generated during inflation dictates the distribution of dark matter haloes in the universe at later times. These haloes attract gas clouds which gravitate to form galaxies and clusters of galaxies that we observe today. In this work, it is shown that in a specific class of inflationary models, called ultra slow-roll inflation, the primordial scalar fluctuations can be nullified at a specific scale so that the corresponding distribution of dark matter haloes will be suppressed over that scale. This effect gets imprinted as a dip in the spectrum of 21-cm lines emitted by hydrogen gas clouds that are captured by these haloes during the Dark Ages. Interestingly, such a dip can be detected by future 21-cm observatories such as an array of radio detectors on the far side of the moon. If detected, such a dip in the signal will confirm an ultra-slow roll model of inflation. This in turn shall have interesting implications for other phenomena predicted by the model such as the amplification of primordial tensor fluctuations that propagate as stochastic gravitational waves.
