FGC 1287 and its enigmatic 250 kpc long HI tail in the outskirts of Abell 1367
(2022-01-17)
We present HI and radio continuum, narrow-band H$\alpha$ imaging, IFU spectroscopy, and X-ray observations of the FGC 1287 triplet projected $\sim$ 1.8 Mpc west of the galaxy cluster Abell 1367. One triplet member, FGC ...
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
(2021-12-01)
What determines the nuclear radio emission in local galaxies? To address this question, we combine optical [O iii] line emission, robust black hole (BH) mass estimates, and high-resolution e-MERLIN 1.5-GHz data, from the ...
LeMMINGs. II. The e-MERLIN legacy survey of nearby galaxies. The deepest radio view of the Palomar sample on parsec scale
(2020-11-17)
We present the second data release of high-resolution ($\leq0.2$ arcsec) 1.5-GHz radio images of 177 nearby galaxies from the Palomar sample, observed with the e-MERLIN array, as part of the LeMMINGs (Legacy e-MERLIN ...
MeerKAT HI commissioning observations of MHONGOOSE galaxy ESO 302-G014
(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 ...
JINGLE - IV. Dust, HI gas and metal scaling laws in the local Universe
(2020-06-02)
Scaling laws of dust, H i gas and metal mass with stellar mass, specific star formation rate and metallicity are crucial to our understanding of the buildup of galaxies through their enrichment with metals and dust. In ...
Calibrating the relation of low-frequency radio continuum to star formation rate at 1 kpc scale with LOFAR
(2018-10-15)
Radio continuum (RC) emission in galaxies allows us to measure star formation rates (SFRs) unaffected by extinction due to dust, of which the low-frequency part is uncontaminated from thermal (free-free) emission. We ...
Radio jets in NGC 4151 where eMERLIN meets HST
(2017-12-21)
We present high-sensitivity eMERLIN radio images of the Seyfert galaxy NGC 4151 at 1.5 GHz. We compare the new eMERLIN images to those from archival MERLIN observations in 1993 to determine the change in jet morphology in ...
Molecular gas and star formation in the Tidal Dwarf Galaxy VCC 2062
(2016-06-01)
The physical mechanisms driving star formation (SF) in galaxies are still not fully understood. Tidal dwarf galaxies (TDGs), made of gas ejected during galaxy interactions, seem to be devoid of dark matter and have a ...
High star formation rates in turbulent atomic-dominated gas in the interacting galaxies IC 2163 and NGC 2207
(2016-05-20)
CO observations of the interacting galaxies IC 2163 and NGC 2207 are combined with HI, Halpha and 24 microns to study the star formation rate (SFR) surface density as a function of the gas surface density. More than half ...
Gas dynamics in tidal dwarf galaxies : disc formation at z=0
(2015-12)
Tidal dwarf galaxies (TDGs) are recycled objects that form within the collisional debris of interacting/merging galaxies. They are expected to be devoid of non-baryonic dark matter, since they can form only from dissipative ...
