NOCTURNE. VI. Hour-timescale radio variability in early-stage active galactic nucleus SDSS J122844.81+501751.2
E. Järvelä, P. Romano, J. Nättilä +7
Recently, a sample of radio-weak active galactic nuclei (AGN) was discovered to exhibit extreme Jy-level radio flares at 37~GHz. The origin of these extraordinary flares remains un…
Simultaneous modeling of FeII emission in the optical and near-infrared in a prototypical Narrow-Line Seyfert 1 galaxy
Denimara Dias dos Santos, Swayamtrupta Panda, Alberto Rodríguez-Ardila +1
This work investigates the FeII emission in active galactic nuclei (AGN), combining observational data from optical and near-infrared (NIR) spectra of the prototypical FeII emitter…
NOCTURNE. I. The radio spectrum of narrow-line Seyfert 1 galaxies
M. Berton, E. Järvelä, S. Chen +8
The origin of the radio emission in active galactic nuclei (AGN) is still debated. Multiple physical mechanisms can contribute to the spectrum at these frequencies, including relat…
Powerful outflows of compact radio galaxies
Bárbara L. Miranda Marques, Alberto Rodríguez-Ardila, Marcos A. Fonseca-Faria +1
Gigahertz Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) sources are compact radio galaxies (RGs), with jets extending up to 20 kpc and ages <10^3 years. They are considere…
First detection of outflowing gas in the outskirts of the broad line region in 1H-0707-495
Alberto Rodriguez-Ardila, Marcos Antonio Fonseca-Faria, Denimara Dias dos Santos +2
We use near-infrared (NIR) spectroscopy covering simultaneously the bands to look for outflowing gas from the nuclear environment of 1H0707-495 taking advantage that this re…
The Narrow Line Region properties of ESO138-G001 unveiled by SOAR/SIFS observations
A. Rodríguez-Ardila, D. May, S. Panda +2
We study in detail the inner 600 pc of the Seyfert 2 galaxy ESO138-G001 by means of the SOAR Integral Field Spectrograph (SIFS) attached to the SOAR telescope. This source is known…
