A common column density threshold for scattering at 3.6 μm and water-ice in molecular clouds
Morten L Andersen,Morten L Andersen,Morten L Andersen,Wing-Fai Thi,Wing-Fai Thi,J. Steinacker,J. Steinacker,J. Steinacker,Nicholas F. H Tothill +8 more
TL;DR: In this article, the authors investigated whether the large grains necessary for e cient scattering at 1 5 m are associated with the abundance of waterice within molecular clouds and cores and found that the scattering e ciency increases as the relative water-ice abundance increases.
A common column density threshold for scattering at 3.6 mum and water-ice in molecular clouds
TL;DR: In this paper, the authors investigate whether the large grains necessary for efficient scattering at 1-5m are associated with the abundance of water-ice within molecular clouds and cores and find that the scattering efficiency increases as the relative waterice abundance increases.
New 6 and 3-cm Radio-Continuum Maps of the Small Magellanic Cloud. Part I - The Maps
Evan J Crawford,Miroslav Filipovic,A. Y. De Horta,Graeme F Wong,Nicholas F. H Tothill,D. Drasković,Jordan D. Collier,Tim J. Galvin +7 more
TL;DR: In this paper, the authors presented 6 and 3-cm radio-continuum maps of the Small Magellanic Cloud (SMC), created with the "peeling" technique and a joint deconvolution.

The Eagle Nebula's fingers - pointers to the earliest stages of star formation?
Glenn J. White,Richard P. Nelson,W. S. Holland,E. I. Robson,Jane Greaves,M. McCaughrean,Göran Pilbratt,D. S. Balser,Tomoharu Oka,S. Sakamoto,Tetsuo Hasegawa,W. H. McCutcheon,Henry E. Matthews,C. V. M. Fridlund,Nicholas F. H Tothill,M. Huldtgren,J. R. Deane +16 more
TL;DR: White et al. as discussed by the authors developed a simple thermal and chemical model of a finger to study the physical environment, which takes into account the external UV illumi-nation ( 1700 G0), and the chemical and thermal structure of the finger.

Characterizing the radio continuum emission from intense starburst galaxies
Timothy J Galvin,Timothy J Galvin,Timothy J Galvin,Nick Seymour,Miroslav Filipovic,Nicholas F. H Tothill,J. Marvil,Guillaume Drouart,M. Symeonidis,Minh Huynh +9 more
TL;DR: In this article, the authors disentangle the thermal and non-thermal emission components of the radio continuum of six ultraluminous infrared galaxies (LFIR > 1012.5 L ) at redshifts of 0.2 ≤ z ≤ 0.5 and 22 IR selected galaxies.
