    AGN activity in Local Luminous Infrared Galaxies

    Luminous Infrared Galaxies (LIR=10^11-10^12Lsun) have star formation rates in the range of ~20-200Msun/yr. In the local Universe ~50% LIRGs show AGN or AGN/SB...

    An Unbiased ULIRG sample at z~2

    I will present a multiwavelength study of a large MIPS selected galaxies and satisfy a certain IRAC color criterion. Stellar population modeling and IRS spectra...

    Emergence of an Ultrared, Ultramassive Galaxy Cluster Core at z = 4

    Recent simulations and observations of massive galaxy cluster evolution predict that the majority of stellar mass buildup happens within cluster members by z =...

    Exploring the Mid-infrared SEDs of Six AGN Dusty Torus Models. I. Synthetic Spectra

    At distances from the active galaxy nucleus where the ambient temperature falls below ̃1500-1800 K, dust is able to survive. It is thus possible to have a large...

    Physical conditions of starburst galaxies from LMT 3-mm spectra

    I will present the first Large Millimiter Telescope spectra of 4 nearby galaxies with known high star formation rates. The individual spectra were acquired with...

    Testing the Unification Model for AGN in the Infrared: are the obscuring tori of Type 1 and 2 Seyferts different?

    I will present new mid-infrared imaging data for a sample of ~20 nearby Seyfert galaxies obtained with T-ReCS and MICHELLE on the Gemini Telescopes at...

    The local dusty environment of active galactic nuclei

    Dust reprocesses the intrinsic radiation of active galactic nuclei (AGN) to emerge at longer wavelengths. The mid-infrared (MIR) luminosity depends broadly on...

    The nuclear infrared emission of low-luminosity active galactic nuclei

    Low-luminosity AGN (LLAGN; LINERs and low-luminosity Seyferts) are present in numerous nearby galaxies and are often suggested to be the "missing link" between...
