Hector Galaxy Survey: Falling in Between - Infalling Galaxies in the Midst of the Abell 3667 Merger

Oğuzhan Çakır, Matt Owers, Gabriella Quattropani +38

Whether cluster mergers enhance ram pressure stripping (RPS) and accelerate member galaxy evolution remains an open question. Here, we investigate galaxy populations in the nearby…

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…

The Impact of Cluster Mergers on Galaxy Properties

Oğuzhan Çakır, Matt S. Owers, Lucas C. Kimmig +4

The impact of galaxy cluster mergers on the properties of the resident galaxies remains poorly understood. In this paper, we investigate the effects of merging environments on star…

Hector Galaxy Survey: Data Processing, Quality Control and Early Science

S. Oh, M. L. P. Gunawardhana, S. M. Croom +52

The Hector Galaxy Survey is a new optical integral field spectroscopy (IFS) survey currently using the AAT to observe up to 15,000 galaxies at low redshift (). The Hector…
