The GECKOS Survey: Resolved, multiphase observations of mass-loading and gas density in the galactic wind of NGC 4666

Barbara Mazzilli Ciraulo, D. B. Fisher, R. Elliott +24

We present a multiphase, resolved study of the galactic wind extending from the nearby starburst galaxy NGC 4666. For this we use VLT/MUSE observations from the GECKOS program and…

The GECKOS Survey: Identifying kinematic sub-structures in edge-on galaxies

A. Fraser-McKelvie, J. van de Sande, D. A. Gadotti +30

The vertical evolution of galactic discs is governed by the sub-structures within them. We examine the diversity of kinematic sub-structure present in the first 12 galaxies observe…

HI within and around observed and simulated galaxy discs -- Comparing MeerKAT observations with mock data from TNG50 and FIRE-2

A. Marasco, W. J. G. de Blok, F. M. Maccagni +12

Atomic hydrogen (HI) is an ideal tracer of gas flows in and around galaxies, and it is uniquely observable in the nearby Universe. Here we make use of wide-field (~1 square degree)…

Uncovering Extraplanar Gas in UGCA 250 with the Ultra-deep MHONGOOSE Survey

Sushma Kurapati, D. J. Pisano, W. J. G. de Blok +28

We use the neutral atomic hydrogen (HI) observations of the edge-on galaxy UGCA 250, taken as part of the MeerKAT HI Observations of Nearby Galactic Objects - Observing Southern Em…

NGC 3259: A Signal for an Untapped Population of Slowly Accreting Intermediate-Mass Black Holes

Kirill A. Grishin, Igor V. Chilingarian, Francoise Combes +4

Low-mass active galactic nuclei (AGNs) can provide important constraints on the formation and evolution of supermassive black holes (SMBHs), a central challenge in modern cosmology…

Searching for HI around MHONGOOSE Galaxies via Spectral Stacking

S. Veronese, W. J. G. de Blok, J. Healy +19

The observed star formation rates of galaxies in the Local Universe suggests that they are replenishing their gas reservoir across cosmic time. Cosmological simulations predict tha…
