We present the first interferometric evidence of CO (1–0) emission in the intragroup starburst (IGS) region of HCG 92 (Stephan’s Quintet). BIMA’s large primary beam fully covers both the IGS region and the dominant group member Seyfert galaxy NGC 7319, as well as partially covering the intruder galaxy NGC 7318B. CO emission of *4 j is detected in all of them. The detection of the CO emission as...

This paper summarizes the evidence of the ultraviolet properties of dust grains found in starburst galaxies. Observations of starburst galaxies clearly show that the 2175 Å feature is weak or absent. This can be the result of radiative transfer effects (mixing the dust and stars) or due to dust grains which do not have this feature. Spherical DIRTY radiative transfer models imply that it is not...

Cosmic ray protons interacting with gas at the mean density of the interstellar medium in starburst galaxies lose energy rapidly via inelastic collisions with ambient nuclei. The resulting pions produce secondary electrons and positrons, high-energy neutrinos, and γ-ray photons. We estimate the cumulative γ-ray emission from starburst galaxies and find a specific intensity at GeV energies of νI...

We have searched for water vapor emission at 183 GHz, redshifted at 157 GHz and 161 GHz, in the two ultraluminous starburst galaxies Mkn 1014 and VIIZw244. Due to the low energy level of the upper state of the 183 GHz transition (≈ 200K), it is expected that the emission regions are extended, as they are in the Orion or W49Nmolecular cloud cores. Since the warm and dense gas, typical of star-fo...

This paper is primarily a study of the effect of a bar on the neutral hydrogen (HI) content of starburst and Seyfert galaxies. We also make comparisons with a sample of " normal " galaxies and investigate how well starburst and Seyfert galaxies follow the fundamental scaling Tully-Fisher (TF) relation defined for normal galaxies. 111 Markarian (Mrk) IRAS galaxies were observed at the Nançay rad...

Ever since the co-existence of an active galactic nucleus (AGN) and a starburst was observationally discovered, there has been a significant controversy over whether there is a physical connection between starbursts and AGNs. If yes, it is a subject of interest to reveal which one triggers another. Here we bring a unique insight onto the subject by identifying 840 galaxies with both a post-star...

The center of M83, a barred starburst galaxy with a double nucleus, has been observed in the CO(J=2–1) and CO(J=3–2) lines with the Submillimeter Array. The molecular gas shows a distribution and kinematics typical for barred galaxies at ∼kpc radii, but reveals unusual kinematics around the double nucleus in the central ∼300 pc. Our CO velocity data show that the visible nucleus in M83 is at le...
