Small and Complex II: Characterizing the Disk and Stellar Envelope of Edge-on Massive Compact Galaxies
A. Schnorr-Müller, K. Slodkowski Clerici, F. Pinna +7
We present multi-component photometric decompositions of -band Hyper Suprime-Cam images for a sample of 75 edge-on massive compact galaxies (MCGs) at , selected as $+2σ…
The First Detection of Forbidden Emission Lines at the Outskirts of the AGN Broad Line Region?
Kelly F. Heckler, Rogemar A. Riffel, Daniel Marsango +3
Double-peaked (DP) broad emission line profiles in active galactic nuclei (AGNs) are often interpreted as signatures of rotating disk-like structures in the broad-line region (BLR)…
Evaluating the efficacy of a data cube treatment procedure for kinematic analyses: application to NGC 3115 and NGC 4699
R. B. Menezes, L. D. B. Sonoda, Patrícia da Silva +5
Data cubes have been increasingly used in astronomy. These data sets, however, are usually affected by instrumental effects and high-frequency noise. In this work, we evaluate the…
Digging deeper into NGC 6868 II: ionized gas and excitation mechanism
João P. V. Benedetti, Rogério Riffel, Tiago Ricci +9
We studied the ionized gas in the inner region ( pc) of the galaxy NGC 6868 using Gemini/GMOS integral field unit observations. Channel maps reveal complex ki…
Spatially resolved spectroscopic observations of gas emission in dwarf galaxies hosting accreting black hole candidate
Kelly F. Heckler, Rogemar A. Riffel, Tiago V. Ricci
Recent studies on dwarf galaxies reveal that some of them harbor a massive black hole (BH), which is believed to have a similar mass of the Supermassive BH "seeds" at early times.…
Massive Compact Quiescent Galaxies in the vs. Plane: Insights from stellar Population Properties
K. Slodkowski Clerici, A. Schnorr-Müller, M. Trevisan +1
We investigated the stellar population properties of a sample of 1858 massive compact galaxies (MCGs) extracted from the SDSS survey. Motivated by previous results showing that old…
The Origin of Massive Compact Galaxies: Lessons from IllustrisTNG
F. S. Lohmann, A. Schnorr-Müller, M. Trevisan +2
We investigate the formation and evolution of z=0 massive compact galaxies (MCGs) in the IllustrisTNG cosmological simulation. We found that, as in observations, MCGs are mainly ol…
Digging deeper into NGC\,6868 I: stellar population
João P. V. Benedetti, Rogério Riffel, Tiago Ricci +8
We use Gemini integral field unit observations to map the stellar population properties in the inner region ( pc) of the galaxy NGC 6868. In order to understa…
IFU observations of the inner 200 pc of NGC 4546: gas rotation, non-circular motions and ionised outflows
Kelly F. Heckler, Tiago V. Ricci, Rogemar A. Riffel
We present a detailed analysis of the ionised gas distribution and kinematics in the inner ~ 200 pc of NGC 4546, host of a Low Luminosity Active Galactic Nucleus (LLAGN). Using GMO…
Active Galactic Nuclei signatures in Red Geyser galaxies from Gemini GMOS-IFU observations
G. S. Ilha, R. A. Riffel, T. V. Ricci +8
Red Geysers are quiescent galaxies with galactic scale ionised outflows, likely due to low-luminosity Active Galactic Nuclei (AGN). We used Gemini GMOS-IFU observations of the inne…
The DIVING Survey -- Deep IFS View of Nuclei of Galaxies -- II. First results: nuclear emission-line properties of the mini-DIVING sample
R. B. Menezes, J. E. Steiner, T. V. Ricci +1
This work presents the first results of the Deep IFS View of Nuclei of Galaxies (DIVING) survey. We analysed the nuclear emission-line spectra of a sub-sample we call…
The DIVING Survey -- Deep IFS View of Nuclei of Galaxies -- I. Definition and Sample Presentation
J. E. Steiner, R. B. Menezes, T. V. Ricci +7
We present the Deep Integral Field Spectrograph View of Nuclei of Galaxies (DIVING) survey, a seeing-limited optical 3D spectroscopy study of the central regions of all 170…
The Puzzling Origin of Massive Compact Galaxies in MaNGA
A. Schnorr-Müller, M. Trevisan, R. Riffel +7
We characterized the kinematics, morphology, and stellar population (SP) properties of a sample of massive compact quiescent galaxies (MCGs, /$M_\odot \le…
Measuring the mass of the supermassive black hole of the lenticular galaxy NGC 4546
T. V. Ricci, J. E. Steiner
Most galaxies with a well-structured bulge host a supermassive black hole (SMBH) in their centre. Stellar kinematics models applied to adaptive optics (AO) assisted integral field…
A panchromatic spatially resolved study of the inner 500pc of NGC1052 -- II: Gas excitation and kinematics
Luis G. Dahmer-Hahn, Rogério Riffel, Tiago V. Ricci +8
We map the optical and near-infrared (NIR) emission-line flux distributions and kinematics of the inner 320535pc of the elliptical galaxy NGC1052. The integral field sp…
Detection of a double-peaked H component from the accretion disc of NGC 4958
T. V. Ricci, J. E. Steiner
Active Galactic Nuclei are objects associated with the presence of an accretion disc around supermassive black holes found in the very central region of galaxies with a well-define…
