Webinar: Black Holes Everywhere– Dr. Omar López-Cruz

December 9, 2020December 11, 2020 Guest Article 0 Comments

< 1 minute read Black holes (BHs) have become mainstream, since the detection of gravitational waves produced by the merger of binary BHs to the image of the shadow of the BH in M87. We have searched for the largest BH in the universe, the obvious place is the center of the brightest cluster galaxies (BCG). We propose that the BCG Holmberg 15A in the cluster Abell 85 could host the largest BH in the local universe, with a mass larger than 10^10 solar masses. Why can they attain larger masses? What is their origin?

Webinar: NAVIGATING WITH THE HELP OF ASTRONOMY IN THE MODERN ERA– Dr. Pragati Pradhan

December 1, 2020December 1, 2020 Guest Article 0 Comments

< 1 minute read Throughout ancient history, humans have taken help of astronomy to navigate on Earth. I will present an overview of how humans are now designing to explore interplanetary space using X-ray pulsars (a.k.a. space GPS). I will also discuss case studies of some animals like dung-beetles use astronomy to navigate in their everyday life. I will touch upon the inspiration that astronomers obtain from structural designs of some animals (e.g., lobsters) to build X-ray spacecrafts with greater observing efficiency.

Webinar: OPTICS & PHOTONICS RESEARCH IN THE COVID-19 & CLIMATE CHANGE – Dr Thomas Baer

November 27, 2020November 27, 2020 Guest Article 0 Comments

2 minutes read The global challenges of the COVID-19 pandemic and the longer term effects of climate change require coordinated efforts by the scientific and engineering communities to provide accurate information to government officials to guide them as they put in place evidenced-based governmental policies to mitigate and adapt to these major challenges. I will discuss recent joint international programs sponsored by the Optical Society (OSA) and the American Geophysical Union (AGU) for developing and deploying photonics instrumentation to measure and monitor greenhouse and air pollution gases in urban settings and an innovative program sponsored by the OSA Foundation for deploying UV-C based safe and effective decontamination equipment for decontaminating personal protection equipment in limited resource setting. These programs are coordinating the activities of international teams of OSA and AGU scientists and engineers and are providing them with the opportunities to productively engage with government officials in their regions and make significant contributions to meeting these global challenges.

Webinar: LASER SPECTROSCOPY AT EXTREME LIMITS – Dr Hanieh Fattahi

November 21, 2020November 21, 2020 Nishant Pathak 0 Comments Laser, optics, physics, talk

< 1 minute read To capture four dimensional movies of electron dynamics in matter, attosecond resolution in time domain and picometer resolution in space are required. This calls for availability of attosecond pulses with kilo-electronvolt pulse energies, which is beyond the state of the art. This talk is devoted to modern methods for generating ultrashort pulses to overcome this barrier. Coherent synthesis of few-cycle pulses at different carrier frequencies allows for engineering the electric field of light with an arbitrary shape and generating sub-cycle pulses (light transients). Such pulses hold promise to generate attosecond pulses at higher photon energies, paving way towards capturing four dimensional movie of electron-dynamic in matter. I discuss this exotic concept and demonstrate the first prototype high-energy field synthesiser based on Yb:YAG, thin-disk laser technology.

Origin and fate of the universe

October 28, 2020October 28, 2020 SUPARNA K. S 0 Comments Big Bang, Cosmos

7 minutes read For centuries, the origin of the universe has been a great mystery for humans. Was there an exact beginning of the universe? Or was it here all the time? These questions remain hypothetical because no one knows exactly how our universe began. On the earth, we are provided with all the resources we need to survive, but still, we look up to the vast infinite universe. Why are we so concerned about outer space this much? Perhaps it’s our mere curiosity that drives us to dive into the mysterious birth of the cosmos. Scientists say that the universe began 14 billion thousand years ago with a massive explosion called the big bang. But, is that real? This article focuses on the basics of cosmology and some important studies regarding the big bang.
