Department of Physics and Astronomy 2015 Summer Lecture Series Presents:
“Validation of the Spectral Calibration of the Planck High Frequency Instrument,”
A lecture by Ms. Pragya Chawla, MSc Candidate, McGill University, former U of L Mitacs-Globalink Undergraduate Researcher
C610, 2:00-2:30pm, Tuesday 18 August 2015
Abstract:
European Space Agency's Planck Telescope, launched in 2009, observed the cosmic microwave background and its anisotropies with greater sensitivity and resolution than any other measurement. By observing the universe in far-infrared, microwave, and high frequency radio domains, Planck has led to a better understanding of several cosmological and astrophysical phenomena such as the origin of cosmic structure and evolution of the early universe, to the interstellar medium and star formation. An overview of Planck, its instrument suite and some of its pioneering observations will be presented along with a discussion of my work that supports increased net confidence in Planck data. My work concentrated on using observations from 2013 Planck data release archive and source catalogues, and comparing them with out-of-band measurements from the WISE (Wide-field Infrared Survey Explorer) public data archive to perform a flight-data based validation of the spectral calibration of the Planck 100 GHz frequency channel.
