High energy gamma-ray sources in the VVV survey - III. Spectroscopic confirmation of an AGN at low Galactic latitudes
Eduardo O. Schmidt, Laura D. Baravalle, Ana Pichel +9
We aim to spectroscopically confirm the nature of VVV-J181258.71-314346.7, a candidate counterpart to the unassociated gamma-ray source 4FGLJ1812.8-3144. This object was selected b…
AGN candidates in the VVV near-IR galaxy catalogue
Laura D. Baravalle, Eduardo O. Schmidt, M. Victoria Alonso +7
The goal of this work is to search for Active Galactic Nuclei (AGN) in the Galactic disc at very low latitudes with |b| 2. For this, we studied the five sources from th…
New GTC Spectroscopic Data and a Statistical Study to Better Constrain the Redshift of the BL Lac RGB J2243+203
D. Rosa González, H. Muriel, Y. D. Mayya +13
We present new spectroscopic data of the BL Lac RGB 2243+203, and its surroundings, obtained with the OSIRIS Multi Object Spectrograph (MOS) mounted in the Gran Telescopio Canarias…
The BL-Lac gamma-ray blazar PKS 0447-439 as a probable member of a group of galaxies at z=0.343
H. Muriel, C. Donzelli, A. C. Rovero +1
The BL-Lac blazar PKS 0447-439 is one of the brightest HE gamma-ray sources that were first detected by Fermi-LAT. It was also detected by H.E.S.S. at VHE gamma-rays, which allowed…
The interstellar medium and the massive stellar content toward the SNR G18.1-0.1 and neighboring HII regions
S. Paron, W. Weidmann, M. E. Ortega +2
We perform a multiwavelength study toward the SNR G18.1-0.1 and nearby several HII regions (infrared dust bubbles N21 and N22, and the HII regions G018.149-00.283 and G18.197-00.18…
