    • The impact of bound stellar orbits and general relativity on the temporal behavior of tidal disruption flares. 
      Dai, Lixin; Escala Astorquiza, Andrés; Coppi, Paolo (The American Astronomical Society, 2013-09-20)
      We have carried out general relativistic particle simulations of stars tidally disrupted by massive black holes. When a star is disrupted in a bound orbit with moderate eccentricity instead of a parabolic orbit, the ...
    • The Nuclear Near-Infrared Spectral Properties of Nearby Galaxies 
      Mason, R. E.; Rodríguez-Ardila, A.; Martins, L.; Riffel, R.; González Martín, O.; Ramos Almeida, C.; Ruschel Dutra, D.; Ho, L. C.; Thanjavur, K.; Flohic, H.; Alonso Herrero, A.; Lira Teillery, Paulina; McDermid, R.; Riffel, R. A.; Schiavon, R. P.; Winge, C.; Hoenig, M. D.; Perlman, E. (2015-03)
      We present spectra of the nuclear regions of 50 nearby (D = 1–92 Mpc, median = 20 Mpc) galaxies of morphological types E to Sm. The spectra, obtained with the Gemini Near-IR Spectrograph on the Gemini North telescope, ...

H.; Yan, H.; Young, S.; Zheng, W. K. (IOP Publishing, 2016)
      During an intensive Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) UV monitoring campaign of the Seyfert 1 galaxy NGC 5548 performed from 2014 February to July, the normally highly correlated far UV continuum ...
    • Spectroscopic aperture biases in inside-out evolving early-type galaxies from CALIFA 
      Gomes, J.; Papaderos, P.; Vilchez, J.; Kehrig, C.; Iglesias Paramo, J.; Breda, I.; Lehnert, M.; Sánchez, S.; Ziegler, B.; dos Reis, S.; Bland Hawthorn, J.; Galbany, Lluis; Bomans, D.; Rosales Ortega, F.; Walcher, C.; Garcia Benito, R.; Marquez, I.; del Olmo, A.; Molla, M.; Marino, R.; Catalán Torrecilla, C.; Gonzalez Delgado, R.; López Sánchez, Ángel R. (EDP SCIENCES, 2016)
      Integral field spectroscopy (IFS) studies based on CALIFA survey data have recently revealed ongoing low-level star formation (SF) in the periphery of a small fraction (similar to 10%) of local early-type galaxies (ETGs), ...
    • Spiral-like star-forming patterns in CALIFA early-type galaxies 
      Gomes, J.; Papaderos, P.; Vilchez, J.; Kehrig, C.; Iglesias Paramo, J.; Breda, I.; Lehnert, M.; Sánchez, S.; Ziegler, B.; dos Reis, S.; Bland Hawthorn, J.; Galbany, Lluis; Bomans, D.; Rosales Ortega, F.; Walcher, C.; García Benito, R.; Marquez, I.; del Olmo, A.; Molla, M.; Marino, R.; Catalan Torrecilla, C.; González Delgado, R. M.; López Sánchez, Ángel R. (EDP SCIENCES, 2016)
      Based on a combined analysis of SDSS imaging and CALIFA integral field spectroscopy data, we report on the detection of faint (24 < mu(r) mag/square" < 26) star-forming spiral-arm-like features in the periphery of three ...
    • The virus-p exploration of nearby galaxies (venga): radial gas inflow andshock excitation in ngc 1042 
      Luo, Rongxin; Hao, Lei; Blanc Mendiberri, Guillermo; Jogee, Shardha; van den Bosch, Remco C. E.; Weinzirl, Tim (IOP Publishing, 2016)
      NGC 1042 is a late-type bulgeless disk galaxy that hosts low-luminosity active galactic nuclei (AGNs) coincident with a massive nuclear star cluster. In this paper, we present the integral field spectroscopy studies of ...
