Thermal balance and comparison of gas and dust properties of dense clumps in the Hi-GAL survey

Manuel Merello, Sergio Molinari, Kazi L. J. Rygl +7

We present a comparative study of physical properties derived from gas and dust emission in a sample of 1068 dense Galactic clumps. The sources are selected from the crossmatch of…

The Effect of Galaxy Interactions on Molecular Gas Properties

Hsi-An Pan, Lihwai Lin, Bau-Ching Hsieh +26

Galaxy interactions are often accompanied by an enhanced star formation rate (SFR). Since molecular gas is essential for star formation, it is vital to establish whether, and by ho…

KMTNet Nearby Galaxy Survey I. : Optimal strategy for low surface brightness imaging with KMTNet

Woowon Byun, Yun-Kyeong Sheen, Luis C. Ho +8

In hierarchical galaxy formation models, galaxies evolve through mergers and accretions. Tidally-disrupted debris from these processes can remain as diffuse, faint structures, whic…

Nuclear starburst activity induced by elongated bulges in spiral galaxies

Eunbin Kim, Sungsoo S. Kim, Yun-Young Choi +4

We study the effects of bulge elongation on the star formation activity in the centers of spiral galaxies using the data from the Sloan Digital Sky Survey Data Release 7. We constr…
