The multi-wavelength Tully-Fisher relation in the TNG50 cosmological simulation
Maarten Baes, Andrea Gebek, Sabelo Kunene +8
The Tully-Fisher relation (TFR) is one of the most important and widely used empirical correlations in extragalactic astronomy. Apart from its importance as a secondary distance in…
The discovery of a z=0.7092 OH megamaser with the MIGHTEE survey
Matt J. Jarvis, Ian Heywood, Sophie M. Jewell +18
We present the discovery of the most distant OH megamaser to be observed in the main lines, using data from the MeerKAT International Giga-Hertz Tiered Extragalactic Exploration (M…
MIGHTEE-HI: The first MeerKAT HI mass function from an untargeted interferometric survey
Anastasia A. Ponomareva, Matt J. Jarvis, Hengxing Pan +17
We present the first measurement of the HI mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MIGHTEE Survey Early Science data covering a period…
MIGHTEE-\HI: Possible interactions with the galaxy NGC~895
Brenda Namumba, Javier Román, Jesus Falcon Barroso +29
The transformation and evolution of a galaxy is strongly influenced by interactions with its environment. Neutral hydrogen (\HI) is an excellent way to trace these interactions. He…
MIGHTEE-HI: The HI mass-stellar mass relation over the last billion years
Hengxing Pan, Matt J. Jarvis, Mario G. Santos +19
We study the relation over the last billion years using the MIGHTEE-HI sample. We first model the upper envelope of the relation with…
MIGHTEE-HI: Evolution of HI scaling relations of star-forming galaxies at
Francesco Sinigaglia, Giulia Rodighiero, Ed Elson +33
We present the first measurements of HI galaxy scaling relations from a blind survey at . We perform spectral stacking of 9023 spectra of star-forming galaxies undetected i…
MIGHTEE-HI: The relation between the HI gas in galaxies and the cosmic web
Madalina N. Tudorache, M. J. Jarvis, I. Heywood +11
We study the 3D axis of rotation (3D spin) of 77 HI galaxies from the MIGHTEE-HI Early Science observations, and its relation to the filaments of the cosmic web. For this HI-select…
MIGHTEE-HI: the HI Size-Mass relation over the last billion years
Sambatriniaina H. A. Rajohnson, Bradley S. Frank, Anastasia A. Ponomareva +15
We present the observed HI size-mass relation of galaxies from the MIGHTEE Survey Early Science data. The high sensitivity of MeerKAT allows us to detect galaxies spanning mo…
MIGHTEE-HI: The baryonic Tully-Fisher relation over the last billion years
Anastasia A. Ponomareva, Wanga Mulaudzi, Natasha Maddox +17
Using a sample of 67 galaxies from the MIGHTEE Survey Early Science data we study the HI-based baryonic Tully-Fisher relation (bTFr), covering a period of one billion years (…
Measuring the baryonic Tully-Fisher relation below the detection threshold
Hengxing Pan, Matt J. Jarvis, Anastasia A. Ponomareva +4
We present a novel 2D flux density model for observed HI emission lines combined with a Bayesian stacking technique to measure the baryonic Tully-Fisher relation below the nominal…
MIGHTEE-HI: Discovery of an HI-rich galaxy group at z = 0.044 with MeerKAT
Shilpa Ranchod, Roger P. Deane, Anastasia A. Ponomareva +13
We present the serendipitous discovery of a galaxy group in the XMM-LSS field with MIGHTEE Early Science observations. Twenty galaxies are detected in HI in this group…
MIGHTEE-HI: The HI emission project of the MeerKAT MIGHTEE survey
Natasha Maddox, Bradley S. Frank, A. A. Ponomareva +19
We present the HI emission project within the MIGHTEE survey, currently being carried out with the newly commissioned MeerKAT radio telescope. This is one of the first deep, blind,…
From light to baryonic mass: the effect of the stellar mass-to-light ratio on the Baryonic Tully-Fisher relation
Anastasia A. Ponomareva, Marc A. W. Verheijen, Emmanouil Papastergis +2
In this paper we investigate the statistical properties of the Baryonic Tully-Fisher relation (BTFr) for a sample of 32 galaxies with accurate distances based on Cepheids and/or TR…
The Multi-Wavelength Tully-Fisher relation with spatially resolved HI kinematics
Anastasia A. Ponomareva, Marc A. W. Verheijen, Reynier F. Peletier +1
In this paper we investigate the statistical properties of the Tully-Fisher relation for a sample of 32 galaxies with measured distances from the Cepheid period-luminosity relation…
A new astrophysical solution to the Too Big To Fail problem - Insights from the MoRIA simulations
Robbert Verbeke, Emmanouil Papastergis, Anastasia A. Ponomareva +2
We test whether advanced galaxy models and analysis techniques of simulations can alleviate the Too Big To Fail problem (TBTF) for late-type galaxies, which states that isolated dw…
Detailed HI kinematics of Tully-Fisher calibrator galaxies
Anastasia A. Ponomareva, Marc A. W. Verheijen, Albert Bosma
We present spatially-resolved HI kinematics of 32 spiral galaxies which have Cepheid or/and Tip of the Red Giant Branch distances, and define a calibrator sample for the Tully-Fish…
Testing core creation in hydrodynamical simulations using the HI kinematics of field dwarfs
Emmanouil Papastergis, Anastasia A. Ponomareva
The majority of recent hydrodynamical simulations indicate the creation of central cores in the mass profiles of low-mass halos, a process that is attributed to star formation-rela…
