Date: 13 Feb 2016, 10:00 to 15:00 HRS IST
Venue: Chandrasekhar Auditorium, ICTS, Bengaluru
The discovery of gravitational waves is a special moment for science. In celebration of this occasion and also to highlight the important contributions made by the Indian scientific community, ICTS-TIFR is organising a day event (10am-3pm) on Saturday, 13 Feb 2016 at its new campus in Hesaraghatta. This event titled "The Universe in a New Light" will consist of talks aimed at a general scientific audience, which will explain the origin of gravitational waves, how they were detected and what we are learning from their detection as well as the new directions that now open up. The speakers include Bala Iyer (Simons Visiting Professor at ICTS-TIFR and Chairperson, IndIGO consortium), C. V. Vishveshwara, P. Ajith (group leader in Astrophysical relativity, ICTS-TIFR), K.G. Arun (CMI), Tarun Souradeep (IUCAA, Pune; Spokesperson, Indigo consortium). They will convey how this discovery opens a completely new window into the universe entirely different from how we have seen the universe hitherto - which has been only through electromagnetic waves (visible light, radio, X-ray etc.). There will also be an interaction with the press and an opportunity for them to talk with the various members of the scientific community present.

In 2015–2016, the Next in Science series focused on frontiers in astronomy and astrophysics. Scholars discussed new interdisciplinary research on what the structure of the universe tells us about particle interactions, gravitational waves from circling black holes, magnetic fields in intergalactic space, and the possibility of life on exoplanets.

“Please Pardon Our Dust” with Doug Finkbeiner | CfA

Many beautiful astronomical images result from starlight being absorbed or scattered by interstellar dust. These processes make for pretty pictures, but also confound astronomers as they try to see through the dust. New efforts are creating a 3-D map of cosmic dust within our galaxy by measuring the colors of nearly 1 billion stars. The resulting data visualizations are not only picturesque, but also crucial to the star-mapping mission of the Gaia satellite and the science of the upcoming Large Synoptic Survey Telescope. Generating this dust map required years of work – but it beats wiping off shelves and knick-knacks!
Doug Finkbeiner is a Harvard professor of physics and of astronomy, and leader of the research group creating a 3-D map of Milky Way dust.

John Asher Johnson, "Hot on the Trail of Warm Planets Around Cool Stars"

source: Harvard University    2016年8月31日
Just three years ago the prospect of finding temperate, rocky worlds around other stars was still the subject of science fiction: none had been found and reasonable estimates put us years or decades away from such a momentous discovery. All of that has changed very recently on the heels of the extraordinarily successful NASA Kepler mission. By searching for the tiny diminutions of starlight indicative of an eclipsing planet, Kepler has produced thousands of new planet candidates orbiting distant stars. Careful statistical analyses have shown that the majority of these candidates are bona fide planets, and the number of planets increases sharply toward Earth-sized bodies. Even more remarkably, many of these planets are orbiting stars right “next door.” Professor Johnson describe the multi-telescope campaign to validate and characterize these tiny planetary systems, and presents some early, exciting results that point the way toward a large sample of Earth-sized planets in the habitable zones of nearby stars.

The New Cosmos: Answering Astronomy’s Big Questions

source: Harvard University     2016年5月24日
Over the past decade, astronomers have answered - or are closing in on the answers to - some of the biggest questions about the universe. David Eicher presents a spectacular exploration of the cosmos that provides you with a balanced and precise view of the latest discoveries. Among the "big science" topics covered in his new book are dark energy, dark matter, water on Mars, the planethood of Pluto, the barred-spiral structure of the Milky Way, and the ubiquitous nature of black holes.
