A molecular gas study of low luminosity radio galaxies
Prandoni, I.; Wilson, T. L.; de Ruiter, H. R. +3 more
We discuss CO spectral line data of a volume-limited sample of 23 nearby ( z < 0.03) low luminosity radio galaxies, selected from the B2 catalogue. We investigate whether the CO properties of our sample are correlated with the properties of the host galaxy, and in particular with the dust component. We find strong evidences for a physical link …
Cold and hot gas in the most HI deficient compact groups
Yun, Min S.; Verdes-Montenegro, Lourdes; Borthakur, Sanchayeeta +2 more
Dense groups of galaxies should be prime sites for galaxy interactions and mergers, and their evolution has been the subject of controversy for 25 years. In order to explain the HI deficiency found in compact groups of galaxies we previously proposed an evolutionary scenario in which the amount of HI decreases with the secular evolutionary state o…
Witnessing the formation of a brightest cluster galaxy at z > 2
Ford, Holland C.; Miley, George K.; Overzier, Roderik A.
We present deep observations taken with the HST advanced camera for surveys of the central massive galaxy in a forming cluster at z = 2.2. The galaxy hosting the powerful radio source MRC 1138-262 is associated with one of the most extensive merger systems known in the early universe. Our HST/ACS image shows many star-forming galaxies merging with…
Ionized gas in starbursts: Case study of M82 and a note on NGC 1275
Gallagher, J. S.
Starbursts can be considered as galaxies where the normal self-regulation between the densities of young stars and the state of the ISM has broken down. This contribution briefly examines how intense modes of star formation influence the ISM, primarily as measured through properties of the warm ionized gas.
Winds from super star clusters: The interstellar environment in the starburst core of M82
Smith, L. J.; Westmoquette, M. S.
We present HST/STIS spectroscopy for two slit positions crossing the starburst core of M82, sampling both clusters and ionized gas at optical wavelengths. The spectra have a spatial resolution of ∼2 pc at M82, allowing us to probe the conditions within the starburst environment in unprecedented detail. The data provide new insights into young clus…
