1 Astronomy 423 at UNM Radio Astronomy Radio Astronomy Intro, part 2 Greg Taylor University of New Mexico Jan 24, 2011 2 G. Taylor, Astr 423 at UNM Announcements Observing proposals for EVLA and VLBA time due tomorrow, Jan 25 by 3pm MT. Just one paragraph (references optional) – I want at least one from everybody (can use today’s suggestions) – Strongly advise against “detection experiments” Graduate credit for properly enrolled Graduate students should happen automatically. If not, then turn in green card to OGS Astronomy 423 at UNM Radio Astronomy More Science with the EVLA Some Possible EVLA Observing Projects 4 G. Taylor, Astr 423 at UNM What are the benefits to doing radio astronomy? 1. can do it easily from the ground, day and night! 2. some objects/processes are easier to detect in the radio compared to other wavelengths cheap, easy to repair, upgrade round the clock observations – efficient observatories - some distant, active galaxies are dominated by radio emission - jets from accretion onto a black hole - interstellar gas clouds between interacting galaxies - magnetic fields 5 G. Taylor, Astr 423 at UNM 6 G. Taylor, Astr 423 at UNM Name that planet observed in the radio with the VLA detection of the magnetic belts around Jupiter synchrotron emission from energetic particles in magnetic fields
