  • Fast and Furious: Shock Heated Gas as the Origin of Spatially Resolved Hard X-Ray Emission in the Central 5 kpc of the Galaxy Merger NGC 6240 
    Wang, Junfeng; Nardini, Emanuele; Fabbiano, Giuseppina; Karovska, Margarita; Elvis, Martin; Pellegrini, Silvia; Max, Claire; Risaliti, Guido; U, Vivian; Zezas, Andreas (2014)
    We have obtained a deep, subarcsecond resolution X-ray image of the nuclear region of the luminous galaxy merger NGC 6240 with Chandra, which resolves the X-ray emission from the pair of active nuclei and the diffuse hot ...
  • The Inner Kiloparsec of Mrk 273 with Keck Adaptive Optics 
    U, Vivian; Medling, Anne; Sanders, David; Max, Claire; Armus, Lee; Iwasawa, Kazushi; Evans, Aaron; Kewley, Lisa; Fazio, Giovanni G. (2013)
    There is X-ray, optical, and mid-infrared imaging and spectroscopic evidence that the late-stage ultraluminous infrared galaxy merger Mrk 273 hosts a powerful active galactic nucleus (AGN). However, the exact location of ...
  • Keck OSIRIS AO LIRG Analysis (KOALA): Feedback in the Nuclei of Luminous Infrared Galaxies 
    U, Vivian; Medling, Anne M.; Inami, Hanae; Armus, Lee; Díaz-Santos, Tanio; Charmandaris, Vassilis; Howell, Justin; Stierwalt, Sabrina; Privon, George C.; Linden, Sean T.; Sanders, David B.; Max, Claire E.; Evans, Aaron S.; Barcos-Muñoz, Loreto; Chiang, Charleston W. K.; Appleton, Phil; Canalizo, Gabriela; Fazio, Giovanni; Iwasawa, Kazushi; Larson, Kirsten; Mazzarella, Joseph; Murphy, Eric; Rich, Jeffrey; Surace, Jason (2019)
    The role of feedback in triggering or quenching star formation and hence driving galaxy evolution can be directly studied with high-resolution integral field observations. The manifestation of feedback in shocks is ...
  • The Lick AGN Monitoring Project 2016: Velocity-resolved Hβ Lags in Luminous Seyfert Galaxies 
    U, Vivian; Barth, Aaron J.; Vogler, H. Alexander; Guo, Hengxiao; Treu, Tommaso; Bennert, Vardha N.; Canalizo, Gabriela; Filippenko, Alexei V.; Gates, Elinor; Hamann, Frederick; Joner, Michael D.; Malkan, Matthew A.; Pancoast, Anna; Williams, Peter R.; Woo, Jong-Hak; Abolfathi, Bela; Abramson, L. E.; Armen, Stephen F.; Bae, Hyun-Jin; Bohn, Thomas; Boizelle, Benjamin D.; Bostroem, Azalee; Brandel, Andrew; Brink, Thomas G.; Channa, Sanyum; Cooper, M. C.; Cosens, Maren; Donohue, Edward; Fillingham, Sean P.; González-Buitrago, Diego; Halevi, Goni; Halle, Andrew; Hood, Carol E.; Horne, Keith; Horst, J. Chuck; Kouchkovsky, Maxime de; Kuhn, Benjamin; Kumar, Sahana; Leonard, Douglas C.; Loveland, Donald; Manzano-King, Christina; McHardy, Ian; Michel, Raúl; Olaes, Melanie Kae B.; Park, Daeseong; Park, Songyoun; Pei, Liuyi; Ross, Timothy W.; Runco, Jordan N.; Samuel, Jenna; Sánchez, Javier; Scott, Bryan; Sexton, Remington O.; Shin, Jaejin; Shivvers, Isaac; Spencer, Chance L.; Stahl, Benjamin E.; Stegman, Samantha; Stomberg, Isak; Valenti, Stefano; Villafaña, L.; Walsh, Jonelle L.; Yuk, Heechan; Zheng, WeiKang (2022)
    We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast double spectrograph on the 3 m Shane telescope at Lick Observatory from 2016 April to 2017 May. Targeting active galactic nuclei ...
