The Relationship Between Molecular Gas and Star Formation in Low-Mass E/S0 Galaxies
Lisa H. Wei, Stuart N. Vogel, Sheila J. Kannappan +3
We consider the relationship between molecular-gas and star-formation surface densities in 19 morphologically defined E/S0s with stellar mass <~ 4x10^10 M_sun, paying particular at…
Lack of Interaction between the Dust Grains and the Anomalous Radio Jet in the Nearby Spiral Galaxy NGC 4258
Seppo Laine, Marita Krause, Fatemeh S. Tabatabaei +1
We obtained Spitzer/IRAC 3.6-8 micron images of the nearby spiral galaxy NGC 4258 to study possible interactions between dust and the radio jet. In our analysis we also included hi…
Warm Molecular Hydrogen Emission in Normal Edge-On Galaxies NGC 4565 and NGC 5907
Seppo Laine, Philip N. Appleton, Stephen T. Gottesman +2
We have observed warm molecular hydrogen in two nearby edge-on disk galaxies, NGC 4565 and NGC 5907, using the Spitzer high-resolution infrared spectrograph. The 0-0 S(0) 28.2 micr…
