Determination of kinematic distances of WISE & SMGPS H II regions in the Galactic plane using SEDIGISM cloud association

Moses Langa, Mark Thompson, Andrew Rigby +7

One of the fundamental requirements for studying and understanding Galactic structure and massive star formation is accurate distances to H II regions. However, most distance assig…

LeMMINGs VII: 5 GHz, 50 mas e-MERLIN observations of a statistically complete sample of nearby AGN

D. R. A. Williams-Baldwin, R. D. Baldi, R. J. Beswick +36

We present 5 GHz e-MERLIN radio images at 50 mas resolution of the nuclear regions of the Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs), the deepest stati…

H II regions and supernova remnants associated with molecular clouds: A pilot study with the SARAO MeerKAT Galactic Plane Survey

Moses O. Langa, Mark A. Thompson, Andrew J. Rigby +5

Massive stars (mass beyond 8 solMass) release vast amounts of energy into the interstellar medium through their stellar winds, photoionising radiation and supernova explosions. The…

Non-thermal Radio Emission from Massive Protostars in the SARAO MeerKAT Galactic Plane Survey

W. O Obonyo, M. G Hoare, S. L Lumsden +7

We present an investigation of the L-band emission from known massive young stellar objects (MYSOs) in the SARAO MeerKAT Galactic Plane Survey to search for non-thermal radio emitt…

The SARAO MeerKAT Galactic Plane Survey filamentary source catalogue

Gwenllian M. Williams, Mark A. Thompson, Mubela Mutale +11

We present a catalogue of filamentary structures identified in the SARAO (South African Radio Astronomy Observatory) MeerKAT 1.3 GHz Galactic Plane Survey (SMGPS). We extract 933 f…

Radio jets in NGC 1068 with e-MERLIN and VLA: structure and morphology

Isaac M. Mutie, David Williams-Baldwin, Robert J. Beswick +7

We present new high-sensitivity e-MERLIN and VLA radio images of the prototypical Seyfert 2 galaxy NGC 1068 at 5, 10 and 21 GHz. We image the radio jet, from the compact components…

LeMMINGs. VI. Connecting nuclear activity to bulge properties of active and inactive galaxies: radio scaling relations and galaxy environment

B. T. Dullo, J. H. Knapen, R. J. Beswick +13

Multiwavelength studies indicate that nuclear activity and bulge properties are closely related, but the details remain unclear. To study this further, we combine $Hubble~Space~Tel…

LeMMINGs. V. Nuclear activity and bulge properties: a detailed multi-component decomposition of -MERLIN Palomar galaxies with

B. T. Dullo, J. H. Knapen, R. J. Beswick +12

[Abridged] We use high-resolution imaging and -MERLIN 1.5-GHz observations of galaxy cores from the LeMMINGs survey to investigate the relation between optical structural…

LeMMINGs. III. The e-MERLIN Legacy Survey of the Palomar sample. Exploring the origin of nuclear radio emission in active and inactive galaxies through the [O III] -- radio connection

R. D. Baldi, D. R. A. Williams, R. J. Beswick +31

What determines the nuclear radio emission in local galaxies? We combine optical [O III] line emission, robust black hole (BH) mass estimates, and high-resolution e-MERLIN 1.5-GHz…

Massive Protocluster of a Periodic Maser Source G188.95+0.89

M. M. Mutie, J. O. Chibueze, K. El Bouchefry +3

We report the results of ongoing monitoring of the 6.7 GHz CHOH masers associated with G188.95+0.89. In these observations five features are periodically varying and at least t…
