The Lick AGN Monitoring Project 2016: Velocity-Resolved Hβ Lags in Luminous Seyfert Galaxies
Vivian U, Aaron J. Barth, H. Alexander Vogler +61
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 April 2016 to M…
Extensive Photometry of V1838 Aql during the 2013 Superoutburst
J. Echevarría, E. de Miguel, J. V. Hernández Santisteban +15
We present an in-depth photometric study of the 2013 superoutburst of the recently discovered cataclysmic variable V1838 Aql and subsequent photometry near its quiescent state. A c…
The Owl and other strigiform nebulae: multipolar cavities within a filled shell
Ma. T. García-Díaz, W. Steffen, W. J. Henney +4
We present the results of long-slit echelle spectroscopy and deep narrow-band imaging of the Owl Nebula (NGC 3587), obtained at the \textit{Observatorio Astronómico Nacional, San P…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
A spectroscopic and photometric study of the planetary nebulae Kn 61 and Pa 5
Ma. T. García-Díaz, D. González-Buitrago, J. A. López +4
We present the first morpho-kinematical analysis of the planetary nebulae Kn 61 and Pa 5 and explore the nature of their central stars. Our analysis is based on high resolution and…
Multiwavelength observations of V479 Andromedae: a close compact binary with an identity crisis
Diego Gonzalez-Buitrago, Gagik Tovmassian, Sergey Zharikov +5
We conducted a multi-wavelength study to unveil the properties of the extremely long-period cataclysmic variable V479 And. We performed series of observations, including moderate t…
