Hector Galaxy Survey: Optical IFU and Chandra Reveal a Low-Luminosity AGN Behind Extended LINER Emission

Kyuseok Oh, Gabriella Quattropani, Pratyush Kumar Das +25

We present evidence that the Hector Galaxy Survey galaxy C901005481609968 (), which exhibits spatially extended LINER-like emission in optical integral-field spe…

Hector Galaxy Survey: Linking the low- and high-mass ends of the initial mass function in star-forming galaxies

Diego Salvador, Andrew Hopkins, Matt Owers +30

The stellar initial mass function (IMF) is a fundamental ingredient in galaxy evolution, linking observed integrated light to galaxy properties. Constraining the full IMF shape bey…

The SAMI Galaxy Survey: Quenching of Star Formation in Clusters III. Ram-Pressure-Affected Galaxy Populations

Oğuzhan Çakır, Matt S. Owers, Luca Cortese +15

Cluster environments influence galaxy evolution by curtailing star formation activity, notably through ram-pressure stripping (RPS). In this study, using spatially resolved spectro…

Large-scale and local environmental drivers of quenching: tracing H concentration in X-ray and optical galaxy groups

Stefania Barsanti, Di Wang, Matthew Colless +11

To explore the environmental mechanisms causing quenching in nearby star-forming galaxies, we study the variation with local and large-scale environments of a star formation concen…

Exploring the spatially resolved initial mass function in SAMI star-forming galaxies

Diego Salvador, Andrew Hopkins, Matt Owers +2

The initial mass function (IMF) is a construct that describes the distribution of stellar masses for a newly formed population of stars. It is a fundamental element underlying all…

Beyond BPT: A New Multi-Dimensional Diagnostic Diagram for Classifying Power Sources Tested Using the SAMI Galaxy Survey

Victor Johnston, Anne Medling, Brent Groves +11

Current methods of identifying the ionizing source of nebular emission in galaxies are well defined for the era of single fiber spectroscopy, but still struggle to differentiate th…
