      Blok, W. J. G. de; Athanassoula, E.; Bosma, Albert; Combes, Francoise; English, J.; Heald, George H.; Kamphuis, P.; Koribalski, B. S.; Meurer, G. R.; Román, J.; Sardone, A.; Verdes-Montenegro, L.; Bigiel, F.; Brinks, E.; Chemin, L.; Fraternali, F.; Jarrett, T.; Kleiner, D.; Maccagni, F. M.; Pisano, D. J.; Serra, P.; Spekkens, K.; Amram, P.; Carignan, C.; Dettmar, R-J; Gibson, B. K.; Holwerda, B. W.; Józsa, G. I. G; Lucero, D. M.; Oosterloo, T. A.; Ramaila, A. J. T.; Ramatsoku, M.; Sheth, K.; Walter, Fabian; Wong, O.I.; Zijlstra, A. A.; Bloemen, S.; Groot, P. J.; Poole, R. Le; Klein-Wolt, M.; Körding, E. G.; McBride, V. A.; Paterson, K.; Pieterse, D. L. A.; Vreeswijk, P.; Woudt, P. A. (2020-09-22)
      We present the results of three commissioning HI observations obtained with the MeerKAT radio telescope. These observations make up part of the preparation for the forthcoming MHONGOOSE nearby galaxy survey, which is a ...

    • A possible signature of the influence of tidal perturbations in dwarf galaxy scaling relations 

      Watkins, A. E.; Salo, H.; Kaviraj, S.; Collins, C. A.; Knapen, J. H.; Venhola, A.; Román, J. (2023-03-02)
      Dwarf galaxies are excellent cosmological probes, because their shallow potential wells make them very sensitive to the key processes that drive galaxy evolution, including baryonic feedback, tidal interactions, and ram ...

    • Preparing for low surface brightness science with the Vera C. Rubin Observatory: Characterisation of tidal features from mock images 

      Martin, G.; Bazkiaei, A. E.; Spavone, M.; Iodice, E.; Mihos, J. C.; Montes, M.; Benavides, J. A.; Brough, S.; Carlin, J. L.; Collins, C. A.; Duc, P. A.; Gómez, F. A.; Galaz, G.; Hernández-Toledo, H. M.; Jackson, R. A.; Kaviraj, S.; Knapen, J. H.; Martínez-Lombilla, C.; McGee, S.; O'Ryan, D.; Prole, D. J.; Rich, R. M.; Román, J.; Shah, E. A.; Starkenburg, T. K.; Watkins, A. E.; Zaritsky, D.; Laigle, C.; Pichon, C.; Armus, L.; Bianconi, M.; Buitrago, F.; Busá, I.; Davis, F.; Demarco, R.; Desmons, A.; García, P.; Graham, A. W.; Holwerda, B.; Hon, D. S. -H.; Khalid, A.; Klehammer, J.; Klutse, D. Y.; Lazar, I.; Nair, P.; Noakes-Kettel, E. A.; Rutkowski, M.; Saha, K.; Sahu, N.; Sola, E.; Vázquez-Mata, J. A.; Vera-Casanova, A.; Yoon, I. (2022-06-01)
      Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Vera C. Rubin Observatory is poised to deliver ...

    • Strategies for optimal sky subtraction in the low surface brightness regime 

      Watkins, A. E.; Kaviraj, S.; Collins, C. C.; Knapen, J. H.; Kelvin, L. S.; Duc, P. -A.; Román, J.; Mihos, J. C. (2024-03-01)
      The low surface brightness (LSB) regime (μg  ≳  26 mag arcsec−2) comprises a vast, mostly unexplored discovery space, from dwarf galaxies to the diffuse interstellar medium. Accessing this regime requires precisely removing ...
