ALMA detection of the dusty object silhouetted against the S0 galaxy NGC 3269 in the Antlia cluster
L. K. Haikala, R. Salinas, T. Richtler +3
An intriguing silhouette of a small dust patch can be seen against the disk of the S0 galaxy NGC 3269 in the Antlia cluster in optical images. The images do not provide any clue as…
Rosette nebula globules: Seahorse giving birth to a star
M. M. Mäkelä, L. K. Haikala, G. F. Gahm
The Rosette Nebula is an HII region ionized mainly by the stellar cluster NGC 2244. Elephant trunks, globules, and globulettes are seen at the interface where the HII region and th…
Rosette Globulettes and Shells in the Infrared
M. M. Mäkelä, L. K. Haikala, G. F. Gahm
Tiny, dense clumps of sub-solar mass called globulettes form in giant galactic HII regions. The young central clusters compress the surrounding molecular shells which break up into…
Mass and motion of globulettes in the Rosette Nebula
Gösta F. Gahm, Carina M. Persson, Minja M. Mäkelä +1
We have investigated tiny molecular clumps in the Rosette Nebula. Radio observations were made of molecular line emission from 16 globulettes identified in a previous optical surve…
