    • Anomalous gas in ESO 149-G003: A MeerKAT-16 view 

      Jozsa, G.I.G; Thorat, K; Serylak, M (Oxford University Press, 2021)
      ESO 149-G003 is a close-by, isolated dwarf irregular galaxy. Previous observations with the ATCA indicated the presence of anomalous neutral hydrogen (H I) deviating from the kinematics of a regularly rotating disc. We ...

    • The baryonic Tully–Fisher relation in the SIMBA simulation 

      Glowacki, M.; Elson, E.; Dave, R. (Oxford University Press, 2020)
      We investigate the Baryonic Tully–Fisher relation (BTFR) in the (100h−1Mpc)3SIMBA hydrodynamical galaxy formation simulation together with a higher resolution (25h−1Mpc)3SIMBA run, for over 10 000 disc-dominated, H I-rich ...

    • Close-up view of a luminous star-forming galaxy at z = 2.95 

      Berta, S; Young, A.J; Cox, P.c (EDP Sciences, 2021)
      Exploiting the sensitivity of the IRAM NOrthern Extended Millimeter Array (NOEMA) and its ability to process large instantaneous bandwidths, we have studied the morphology and other properties of the molecular gas and dust ...

    • Fitting power-law distributions to data with measurement errors 

      Koen, Chris; Kondlo, L (Oxford University Press, 2009)
      If X, which follows a power-law distribution, is observed subject to Gaussian measurement error e, thenX+e is distributed as the convolution of the power-lawand Gaussian distributions. Maximum-likelihood estimation of ...

    • MIGHTEE-H I: the first MeerKAT H I mass function from an untargeted interferometric survey 

      Jarvis, Matt J; Pan, Hengxing; Ponomareva, Anastasia A; Maddox, Natasha (Oxford University Press, 2023)
      We present the first measurement of the H I mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MeerKAT International GigaHertz Tiered Extragalactic Exploration (MIGHTEE) Survey Early ...

    • NOEMA redshift measurements of bright Herschel galaxies 

      Marchetti, L.; Neri, R.; Cox, P. (EDP Sciences, 2020)
      Using the IRAM NOrthern Extended Millimeter Array (NOEMA), we conducted a program to measure redshifts for 13 bright galaxies detected in the Herschel Astrophysical Large Area Survey with S500 μm ≥ 80 mJy. We report reliable ...

    • The origin of the dust extinction curve in milky way-like galaxies 

      Davé, Romeel; Vogelsberger, M.; Li, Q; Torrey, P.; Narayanan, D. (Oxford University Press, 2021)
      We develop a cosmological model for the evolution of dust grains in galaxies with a distribution of sizes in order to understand the origin of the Milky Way dust extinction curve. Our model considers the formation of active ...

    • The redshift evolution of the baryonic Tully-Fisher relation in SIMBA 

      Glowacki, M; Elson, E; Dav´e, R (Oxford university press, 2021)
      The baryonic Tully–Fisher relation (BTFR) is an important tool for constraining galaxy evolution models. As 21-cm HI emission studies have been largely restricted to low redshifts, the redshift evolution of the BTFR is ...
