Lezing over radioastronomie in het Engels

Op woensdag 20 februari is er een zeer interessante lezing over radioastronomie in de filmzaal van de Jan Paagman Sterrenwacht aan de Ostaderstraat 28 in Asten.

De lezing, die om 20.00 uur begint, wordt verzorgd door Prasad Peeyush en zal in het Engels zijn.

Leden van de Jan Paagman Sterrenwacht hebben gratis toegang.

Crazy Radio Astronomy: Offering the sharpest view of the farthest, oldest and fiercest celestial objects.

Radio astronomy is the sub-field of astronomy dealing with studying the Radio emission from celestial objects. It is extremely young,  starting with an accidental discovery of huge significance in  1933, but still routinely revolutionizes our understanding of the universe. Four Nobel prizes have been awarded to the field till now, but its influence is far wider, ranging from WiFi, to medical imaging.

 Due to radio waves being minimally scattered by interstellar gas and dust, radio astronomy allows us to peer into the hearts of galaxies and stars. The achieved unprecedented resolutions (spatial, temporal and spectral), and sensitivities allows us to see the farthest and oldest sources.

In this talk, I will give a summary of the amazing achievements of Radio Astronomy, and the advances in instrumentation and techniques driving them. This includes craziness such as 'software telescopes', stopping time, and turning the entire earth into a telescope!

Suggested Audience: High-school level physics, engineering mindset.

About the speaker: Peeyush Prasad obtained his Ph.D. in Radio Astronomical instrumentation in 2012 from the Raman Research Institute, Bangalore, India. His work related to hardware and software approaches to expand sensitivities of the Ooty Radio Telescope in India.

He arrived in NL to work on imaging algorithms on the premier Dutch radio telescope, the LOFAR. He also contributed to the upgrade of the Westerbork Radio Telescope while working at ASTRON. Peeyush currently works at ASML B.V, in Eindhoven.
