Nearby galaxies in the LOFAR Two-metre Sky Survey : I. Insights into the non-linearity of the radio–SFR relation
(2022-08-08)
Context. Cosmic rays and magnetic fields are key ingredients in galaxy evolution, regulating both stellar feedback and star formation. Their properties can be studied with low-frequency radio continuum observations, free ...
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 ...
Exploring the making of a galactic wind in the star-bursting dwarf irregular galaxy IC 10 with LOFAR
(2018-05-11)
Low-mass galaxies are subject to strong galactic outflows, in which cosmic rays may play an important role; they can be best traced with low-frequency radio continuum observations, which are less affected by spectral ageing. ...
Herschel Spectroscopic Observations of Little Things Dwarf Galaxies
(2016-01-04)
We present far-infrared (FIR) spectral line observations of five galaxies from the Little Things sample: DDO 69, DDO 70, DDO 75, DDO 155, and WLM. While most studies of dwarfs focus on bright systems or starbursts due to ...
High-resolution mass models of dwarf galaxies from LITTLE THINGS
(2015-06)
We present high-resolution rotation curves and mass models of 26 dwarf galaxies from LITTLE THINGS. LITTLE THINGS is a high-resolution Very Large Array HI survey for nearby dwarf galaxies in the local volume within 11 Mpc. ...
The non-thermal superbubble in IC 10 : the generation of cosmic ray electrons caught in the act
(2015-02-01)
Superbubbles are crucial for stellar feedback, with supposedly high (of the order of 10 per cent) thermalization rates. We combined multiband radio continuum observations from the Very Large Array (VLA) with Effelsberg ...
The Radio Continuum-Star Formation Rate Relation in WSRT SINGS Galaxies
(2014-04-02)
We present a study of the spatially resolved radio continuum–star formation rate (RC–SFR) relation using stateof-the-art star formation tracers in a sample of 17 THINGS galaxies. We use SFR surface density (ΣSFR) maps ...
Little Things
(2012-11)
We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The H I Nearby Galaxy Survey), which is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 ...
The JCMT Nearby Galaxies Legacy Survey - VIII : CO data and the L -L correlation in the SINGS sample
(2012-08-21)
The James Clerk Maxwell Telescope Nearby Galaxies Legacy Survey (NGLS) comprises an Hi-selected sample of 155 galaxies spanning all morphological types with distances less than 25Mpc. We describe the scientific goals of ...
