Tracing neutral hydrogen in UGCA 320: A MHONGOOSE perspective on an edge-on dwarf galaxy in a group environment
Nikki Zabel, D. J. Pisano, Sushma Kurapati +8
We present a detailed analysis of the neutral atomic gas (HI) in the dwarf galaxy UGCA 320, observed with the MeerKAT telescope as part of the MHONGOOSE (MeerKAT HI Observations of…
Mechanisms Affecting Galaxies Nearby and Environmental Trends (MAGNET)
Benedetta Vulcani, Gabriella De Lucia, Daria Zakharova +28
[ABRIDGED] Galaxy evolution is shaped by internal and external mechanisms that regulate the baryon cycle and star formation activity. We present a theoretical framework based on th…
Stars and ionized gas in UGCA 320: a nearby gas-rich, dwarf Irregular galaxy
Adebusola B. Alabi, S. Ilani Loubser, Moses K. Mogotsi +1
UGCA 320 is a gas-rich dwarf irregular galaxy which belongs to a nearby, relatively isolated group of dwarf galaxies. Here, we combine multi-band HST imaging data with deep long-sl…
SALT spectroscopic follow-up of the G4Jy Sample
Sarah V. White, Kshitij Thorat, Moses Mogotsi +9
The GLEAM 4-Jy (G4Jy) Sample is a thorough compilation of the 'brightest' radio sources in the southern sky (Declination < 30 deg), as measured at 151 MHz (S > 4.0 Jy) with the Mur…
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…
Measures of luminous and dark matter in galaxies across time
Jonathan Freundlich, Gauri Sharma, Sabine Thater +14
Dark matter is one of the pillars of the current standard model of structure formation: it is assumed to constitute most of the matter in the Universe. However, it can so far only…
MHONGOOSE -- A MeerKAT Nearby Galaxy HI Survey
W. J. G. de Blok, J. Healy, F. M. Maccagni +57
The MHONGOOSE (MeerKAT HI Observations of Nearby Galactic Objects: Observing Southern Emitters) survey maps the distribution and kinematics of the neutral atomic hydrogen (HI) gas…
The [OIII] profiles of far-infrared active and non-active optically-selected green valley galaxies
Antoine Mahoro, Petri Väisänen, Mirjana Pović +8
We present a study of the line profile in a sub-sample of 8 active galactic nuclei (AGN) and 6 non-AGN in the optically-selected green valley at $\rm{z\,<\,0.5…
A Peculiar Type~II QSO Identified via Broad-band Detection of Extreme Nebular Line Emission
Yu-Heng Lin, Claudia Scarlata, Matthew Hayes +5
We present S82-20, an unusual redshift 3 object identified in SDSS-Stripe 82 broad-band images. The rest-frame ultraviolet spectrum of S82-20 shows emission lines from hig…
An Overview of the MHONGOOSE Survey: Observing Nearby Galaxies with MeerKAT
W. J. G. de Blok, E. A. K. Adams, P. Amram +65
MHONGOOSE is a deep survey of the neutral hydrogen distribution in a representative sample of 30 nearby disk and dwarf galaxies with HI masses from 10^6 to ~10^{11} M_sun, and lumi…
