  1. GalaxiesSylvain Veilleux • My Interests: • Galaxy and black hole formation and evolution • Origin of starburst and AGN activity • Role of galaxy mergers • Impact of feedback processes • Instrumentation for ground-based optical/infrared telescopes • Maryland-Magellan Tunable Filter (MMTF) • NOAO Extremely Wide Field Infrared Mosaic (NEWFIRM) • Astrophotonics • Current team @ Maryland: • PhD students: Mike Koss (shared), Mike McDonald, Hannah Krug, Alex McCormick • Postdoc: Stacy Teng (shared), Margaret Trippe (shared) • Faculty: Stuart Vogel, Rich Mushotzky, Chris Reynolds • GSFC: Neil Gehrels, Harvey Moseley, Alexander Kutyrev, John Mather

  2. Important Issues Arp 220 • Ultraluminous Infrared Galaxies (ULIRGs): near & far • Spheroids in formation • Black hole growth • Galactic winds Jin Koda

  3. QUEST: Quasar and ULIRG Evolution STudy • Ground-based optical/near-infrared images and spectra • VLT/Keck NIR spectroscopy (Dasyra et al. 2006) • HST/NICMOS imaging (Veilleux, Kim, et al. 2009a) • Spitzer Space Telescope (Veilleux, Rupke, et al. 2009b) • Herschel Space Telescope (Humboldt Senior Award @ MPE) [NEW!] • Chandra/XMM/Suzaku (Stacy Teng PhD Thesis) • CARMA(Ashley Zauderer PhD Thesis)

  4. Maryland-Magellan Tunable Filter (http://www.astro.umd.edu/~veilleux/mmtf) Tunable filter for IMACS on the Baade 6.5m telescope with broad wavelength coverage (~ 5000 – 9300 Å), bandwidth (~ 5 – 15 Å) and wide FOV (27) • PI: S. Veilleux (U. Maryland) • Co-PIs: J. Bland-Hawthorn (AAO), A. Dressler (OCIW), M. Rauch (OCIW), & S. Vogel (U. Maryland) • Co-Is: B. Bigelow (OCIW / U. Michigan), M. McDonald (Maryland), D. Rupke (IfA), P. Shopbell (Caltech), B. Sutin (OCIW/Skewray), I. Thompson (OCIW), B. Weiner (Arizona), & R. Weymann (OCIW) • Additional Technical Support (OCIW): A. Bagish, C. Birk, T. Hare, D. Osip, F. Perez • Funding Agency: NSF/ATI (instrument), NSF/EXC(science x 2)

  5. Magellan Telescope IMACS

  6. Galaxy Groups and Clusters(PhD Thesis M. McDonald) (McDonald & Veilleux 2009)

  7. (PI: R. Probst, NOAO; Maryland-NOAO Collaboration) NEWFIRM is … An infrared camera project • 28 arcmin field of view • 0.4 arcsec/pixel resolution • 1-2.5 micron capability • 4-m telescopes sensitivity Integrated with other projects • ORION • MONSOON • Pipeline (Maryland) • Science archive (Maryland) To form a system for • Deep wide field surveys • High efficiency observing • Rapid data turnaround • Public data access

  8. Search for z = 7.7 Lyα emitting galaxies using ultra-narrowband filters(PhD Thesis of H. Krug) ~85% center-to-edge Center of field

  9. M 82 Galactic Winds • Veilleux, Cecil, & Bland-Hawthorn, 2005, ARAA, 43, 769 +

  10. Important Questions • How common are galactic winds? • What is the impact of galactic winds on • Galaxy evolution? • Galaxy formation? • The intergalactic medium?

  11. Dust Outflow: SST IRAC (Engelbracht et al. 2006)

  12. Dust Outflow 2nd-year project of Alex McCormick: Search for dusty galactic winds in the Spitzer archive • Importance: dM/dtdust ~ 1% dM/dtneutral ? • Implications: intergalactic dust?(e.g., Coma ICM; Stickel+98) 850 m

  13. Molecular Gas in Galactic Winds Archetype: M82 + Ionized Gas Warm Molecular Gas (Smith, Gallagher, & Westmoquette ’05) (SV, Rupke, & Swaters ‘09)

  14. Molecular Outflows (PhD thesis of A. McCormick) • Search for warm H2 in local galactic winds from deep NEWFIRM imaging [Data already obtained] • Spitzer survey [on-going] • Very deep Herschel data on local galactic winds [NEW!] 850 m
