Calibrating the relation of low-frequency radio continuum to star formation rate at 1 kpc scale with LOFAR

Heesen, V.; E., Buie II; Huff, C. J.; Perez, L. A.; Woolsey, J. G.; Rafferty, D. A.; Basu, A.; Beck, R.; Brinks, E.; Horellou, C.; Scannapieco, E.; Brüggen, M.; Dettmar, R. -J.; Sendlinger, K.; Nikiel-Wroczyński, B.; Chyży, K. T.; Best, P.N.; Heald, George H.; Paladino, R. (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

Heesen, V.; Rafferty, D. A.; Horneffer, A.; Beck, R.; Basu, A.; Westcott, J.; Hindson, L.; Brinks, E.; Chyży, K. T.; Scaife, A. M. M.; Brüggen, M.; Heald, George; Fletcher, A.; Horellou, C.; Tabatabaei, F. S.; Paladino, R.; Nikiel-Wroczyński, B.; Hoeft, M.; Dettmar, R. -J. (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. ...

Abell 1367: a high fraction of late-type galaxies displaying HI morphological and kinematic perturbations

Scott, T. C.; Brinks, E.; Cortese, L.; Boselli, A.; Bravo-Alfaro, H. (2018-04-21)

To investigate the effects the cluster environment has on late-type galaxies (LTGs), we studied HI perturbation signatures for all Abell 1367 LTGs with HI detections. We used new Very Large Array HI observations combined ...

Radio jets in NGC 4151 where eMERLIN meets HST

Williams, D. R. A.; McHardy, I. M.; Baldi, R. D.; Beswick, R. J.; Argo, M. K.; Dullo, B. T.; Knapen, J. H.; Brinks, E.; Fenech, D. M.; Mundell, C.G.; Muxlow, T.W.B.; Panessa, F.; Rampadarath, H.; Westcott, J. (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

Lisenfeld, U.; Braine, J.; Duc, P. A.; Boquien, M.; Brinks, E.; Bournaud, F.; Lelli, F.; Charmandaris, V. (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

Elmegreen, Bruce G.; Kaufman, Michele; Bournaud, Frederic; Elmegreen, Debra Meloy; Struck, Curtis; Brinks, E.; Juneau, Stephanie (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 ...

Herschel Spectroscopic Observations of Little Things Dwarf Galaxies

Cigan, P.; Young, L.; Cormier, D.; Lebouteiller, V.; Madden, S.; Hunter, D.; Brinks, E.; Elmegreen, B.; Schruba, A.; Heesen, V. (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 ...

Gas dynamics in tidal dwarf galaxies : disc formation at z=0

Lelli, F.; Duc, P. -A.; Brinks, E.; Bournaud, F.; McGaugh, S. S.; Lisenfeld, U.; Weilbacher, P. M.; Boquien, M.; Revaz, Y.; Braine, J.; Koribalski, B. S.; Belles, P.E. (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 ...

Highly perturbed molecular gas in infalling cluster galaxies : the case of CGCG97-079

Scott, T.C.; Usero, A.; Brinks, E.; Bravo-Alfaro, H.; Cortese, L.; Boselli, A.; Argudo-Fernandez, M. (2015-10-11)

We report on CO (J = 2 → 1) mapping with the IRAM 30-m HEtrodyne Receiver Array (HERA) of CGCG 97-079, an irregular galaxy in the merging galaxy cluster Abell 1367 (z = 0.022). We find that ˜80 per cent of the detected CO ...

Variations in the Star Formation Efficiency of the Dense Molecular Gas across the Disks of Star-Forming Galaxies

Usero, Antonio; Leroy, Adam K.; Walter, Fabian; Schruba, Andreas; García-Burillo, Santiago; Sandstrom, Karin; Bigiel, Frank; Brinks, E.; Kramer, Carsten; Rosolowsky, Erik; Schuster, Karl-Friedrich; de Blok, W.J.G. (2015-10)

We present a new survey of HCN(1-0) emission, a tracer of dense molecular gas, focused on the little-explored regime of normal star-forming galaxy disks. Combining HCN, CO, and infrared (IR) emission, we investigate the ...
