Oxyster: A Circumgalactic Low-ionization Oxygen Nebula next to a Starburst Galaxy at
Pengjun Lu, Mingyu Li, Dalya Baron +3
Extended emission line nebulae around galaxies or active galactic nuclei (AGNs) provide a unique window to investigate the galactic ecosystem through the circumgalactic medium (CGM…
Not so windy after all: MUSE disentangles AGN-driven winds from merger-induced flows in rapidly-transitioning galaxies
Dalya Baron, Hagai Netzer, Dieter Lutz +2
Post-starburst galaxies are believed to be in a rapid transition between major merger starbursts and quiescent ellipticals, where AGN feedback is suggested as one of the processes…
Star formation and molecular gas properties of post-starburst galaxies
Dalya Baron, Hagai Netzer, K. Decker French +3
Post-starburst galaxies are believed to be in a rapid transition between major merger starbursts and quiescent ellipticals. Their optical spectrum is dominated by A-type stars, sug…
Multi-phase outflows in post starburst E+A galaxies -- I. General sample properties and the prevalence of obscured starbursts
Dalya Baron, Hagai Netzer, Dieter Lutz +2
E+A galaxies are believed to be a short phase connecting major merger ULIRGs with red and dead elliptical galaxies. Their optical spectrum suggests a massive starburst that was que…
AGN-driven outflows and the AGN feedback efficiency in young radio galaxies
F. Santoro, C. Tadhunter, D. Baron +2
Active galactic nuclei (AGN) feedback operated by the expansion of radio jets can play a crucial role in driving gaseous outflows on galaxy scales. Galaxies hosting young radio AGN…
Multi-phase outflows in post starburst E+A galaxies -- II. A direct connection between the neutral and ionized outflow phases
Dalya Baron, Hagai Netzer, Ric I. Davies +1
Post starburst E+A galaxies are systems that hosted a powerful starburst that was quenched abruptly. Simulations suggest that these systems provide the missing link between major m…
Ionized outflows in local luminous AGN: what are the real densities and outflow rates?
R. Davies, D. Baron, T. Shimizu +23
We report on the determination of electron densities, and their impact on the outflow masses and rates, measured in the central few hundred parsecs of 11 local luminous active gala…
The multiphase gas structure and kinematics in the circumnuclear region of NGC 5728
T. Taro Shimizu, R. I. Davies, D. Lutz +22
We report on our combined analysis of HST, VLT/MUSE, VLT/SINFONI, and ALMA observations of the local Seyfert 2 galaxy, NGC 5728 to investigate in detail the feeding and feedback of…
Discovering AGN-driven winds through their infrared emission: II. Mass outflow rate and energetics
Dalya Baron, Hagai Netzer
The global influence of AGN-driven outflows remains uncertain, due to a lack of large samples with accurately-determined outflow properties. In the second paper of this series, we…
Black hole mass estimation for Active Galactic Nuclei from a new angle
Dalya Baron, Brice Ménard
The scaling relations between supermassive black holes and their host galaxy properties are of fundamental importance in the context black hole-host galaxy co-evolution throughout…
Discovering AGN-driven winds through their infrared emission: I. General method and wind location
Dalya Baron, Hagai Netzer
Large scale outflows of different gas phases are ubiquitous in the host galaxies of active galactic nuclei (AGN). Despite their many differences, they share a common property - the…
Direct evidence of AGN-feedback: a post starburst galaxy stripped of its gas by AGN-driven winds
Dalya Baron, Hagai Netzer, J. Xavier Prochaska +7
Post starburst E+A galaxies show indications of a powerful starburst that was quenched abruptly. Their disturbed, bulge-dominated morphologies suggest that they are merger remnants…
Evidence of ongoing AGN-driven feedback in a quiescent post starburst E+A galaxy
Dalya Baron, Hagai Netzer, Dovi Poznanski +2
Post starburst E+A galaxies are thought to have experienced a significant starburst that was quenched abruptly. Their disturbed, bulge-dominated morphologies suggest that they are…
The weirdest SDSS galaxies: results from an outlier detection algorithm
Dalya Baron, Dovi Poznanski
How can we discover objects we did not know existed within the large datasets that now abound in astronomy? We present an outlier detection algorithm that we developed, based on an…
Evidence that most type 1 AGN are reddened by dust in the host ISM
Dalya Baron, Jonathan Stern, Dovi Poznanski +1
The typical optical-UV continuum slopes observed in many type 1 AGN are redder than expected from thin accretion disk models. A possible resolution to this conundrum is that many A…
Using machine learning to classify the diffuse interstellar bands
Dalya Baron, Dovi Poznanski, Darach Watson +3
Using over a million and a half extragalactic spectra we study the correlations of the Diffuse Interstellar Bands (DIBs) in the Milky Way. We measure the correlation between DIB st…
Dusting off the diffuse interstellar bands: DIBs and dust in extragalactic SDSS spectra
Dalya Baron, Dovi Poznanski, Darach Watson +2
Using over a million and a half extragalactic spectra we study the properties of the mysterious Diffuse Interstellar Bands (DIBs) in the Milky Way. These data provide us with an un…
