Jet-driven shocks and turbulence in radio-loud Active Galactic Nuclei observed with JWST MIRI/MRS

Rogemar A. Riffel, Gabriel L. Souza-Oliveira, Luis Colina +34

Jet-cloud interactions are a key manifestation of Active Galactic Nucleus (AGN) feedback on nuclear scales, distinct from the large-scale radio-mode feedback that suppresses gas co…

Towards Precision Cosmology With Improved PNLF Distances Using VLT-MUSE. III. Impact of Stellar Populations in Early-Type Galaxy

Azlizan A. Soemitro, Lucas M. Valenzuela, Martin M. Roth +5

Distance measurements using the planetary nebula luminosity function (PNLF) rely on the bright-end power-law cut-off magnitude (), which is defined by a number of the [OIII]$\…

The interplay between radio AGN activity and their host galaxies

Guilherme S. Couto, Thaisa Storchi-Bergmann

Radio activity in AGN (Active Galactic Nuclei) produce feedback on the host galaxy via the impact of the relativistic jets on the circumnuclear gas. Although radio jets can reach u…

VALES VIII: Weak ionized gas outflows in star-forming galaxies at traced with VLT/MUSE

Guilherme S. Couto, Thomas M. Hughes, Médéric Boquien +4

We characterize the ionized gas outflows in 15 low-redshift star-forming galaxies, a Valparaíso ALMA Line Emission Survey (VALES) subsample, using MUSE integral field spectroscopy…

Exploring the AGN-Merger Connection in Arp 245 I: Nuclear Star Formation and Gas Outflow in NGC 2992

Muryel Guolo-Pereira, Daniel Ruschel-Dutra, Thaisa Storchi-Bergmann +5

Galaxy mergers are central to our understanding of galaxy formation, especially within the context of hierarchical models. Besides having a large impact on the star formation histo…

Determining star-formation rates in Active Galactic Nuclei hosts via stellar population synthesis

Rogério Riffel, Nicolas D. Mallmann, Gabriele S. Ilha +10

The effect of active galactic nuclei (AGN) feedback on the host galaxy, and its role in quenching or enhancing star-formation, is still uncertain due to the fact that usual star-fo…

Powerful ionized gas outflows in the interacting radio galaxy 4C +29.30

Guilherme S. Couto, Thaisa Storchi-Bergmann, Aneta Siemiginowska +2

We investigate the ionized gas excitation and kinematics in the inner kpc of the merger radio galaxy 4C +29.30. Using optical integral field spectroscopy wit…

Diffuse ionized gas and its effects on nebular metallicity estimates of star-forming galaxies

N. Vale Asari, G. S. Couto, R. Cid Fernandes +5

We investigate the impact of the diffuse ionized gas (DIG) on abundance determinations in star-forming (SF) galaxies. The DIG is characterised using the H equivalent width ($W_{…

Diffuse ionized gas in galaxies across the Hubble sequence at the CALIFA resolution

E. A. D. Lacerda, R. Cid Fernandes, G. S. Couto +7

We use spatially resolved spectroscopy from the Calar Alto Legacy Field Area (CALIFA) survey to study the nature of the line emitting gas in galaxies of different Hubble types, foc…

K band SINFONI spectra of two SMGs: upper limits to the un-obscured star formation from [O II] optical emission line searches

Guilherme S. Couto, Luis Colina, Javier Piqueras López +2

We present deep SINFONI K band integral field spectra of two submillimeter (SMG) galaxy systems: BR 1202-0725 and J1000+0234, at and respectively. Spectra extracted…

Ionized gas kinematics within the inner kiloparsec of the Seyfert galaxy NGC 1365

Davide Lena, Andrew Robinson, Thaisa Storchi-Bergmann +3

We observed the nuclear region of the galaxy NGC 1365 with the integral field unit of the Gemini Multi Object Spectrograph mounted on the GEMINI-South telescope. The field of view…

Integral Field Spectroscopy of the circumnuclear region of the Radio Galaxy Pictor A

Guilherme S. Couto, Thaisa Storchi-Bergmann, Andrew Robinson +4

We present optical integral field spectroscopy of the inner kpc of the broad-line radio galaxy Pictor A, at a spatial resolution of pc. Line emis…
