Markarian (Mkn) 297 is a complex system with two interacting galaxies. Observations were made with ISO using ISOCAM, ISOPHOT and LWS. We present ISOCAM maps at 6.7, 7.7, 12 and 14.…
An ISOCAM survey through gravitationally lensing galaxy clusters. II. The properties of infrared galaxies in the A2218 field
A. Biviano, L. Metcalfe, B. McBreen +10
We observed the cluster Abell 2218 (z=0.175), with ISOCAM on board the Infrared Space Observatory, using two filters with reference wavelengths of 6.7 and 14.3 microns. We detected…
An ISOCAM survey through gravitationally lensing galaxy clusters
L. Metcalfe, J. -P. Kneib, B. McBreen +11
ISOCAM was used to perform a deep survey through three gravitationally lensing clusters of galaxies. Nearly seventy sq. arcmin were covered over the clusters A370, A2218 and A2390.…
Dust Temperatures in the Infrared Space Observatory Atlas of Bright Spiral Galaxies
George J. Bendo, Robert D. Joseph, Martyn Wells +11
We examine far-infrared and submillimeter spectral energy distributions for galaxies in the Infrared Space Observatory Atlas of Bright Spiral Galaxies. For the 71 galaxies where we…
[C II] emission and star formation in late-type galaxies. II A model
D. Pierini, K. J. Leech, H. J. Voelk
We study the relationship between gas cooling via the [C II] (158 micron) line emission and dust cooling via the far-IR continuum emission on the global scale of a galaxy in normal…
Star Formation in the ISO Atlas of Spiral Galaxies
George J. Bendo, Robert D. Joseph, Martyn Wells +11
We investigate star formation along the Hubble sequence using the ISO Atlas of Spiral Galaxies. Using mid-infrared and far-infrared flux densities normalized by K-band flux densiti…
ISO observations of Hickson Compact Group 31 with the central Wolf-Rayet galaxy NGC 1741
B. O'Halloran, L. Metcalfe, B. McBreen +5
Hickson Compact Group (HCG) 31, consisting of the Wolf-Rayet galaxy NGC 1741 and its irregular dwarf companions, was observed using the Infrared Space Observatory. The deconvolved…
Far-Infrared photometry of a statistical sampleof late-type Virgo Cluster galaxies
Richard J. Tuffs, Cristina C. Popescu, Daniele Pierini +6
We present deep diffraction-limited far-infrared (FIR) strip maps of a sample of 63 galaxies later than S0 and brighter than B_T 16.8, selected from the Virgo Cluster Catalogue of…
ISO Observations of the dusty quasar BR1202-0725
K. J. Leech, L. Metcalfe, B. Altieri
We present mid- and far-IR photometry of the high-redshift (z=4.69) dusty quasar BR1202-0725. The quasar was detected in the near-IR, at a flux level (0.7+/-0.2 mJy) consistent wit…
Gas cooling within the diffuse ISM of late-type galaxies
D. Pierini, J. Lequeux, A. Boselli +2
We combine observations of spiral galaxies in the [CII] line at 158 micron, made with the Long Wavelength Spectrometer aboard ISO, with previous data from the Kuiper Airborne Obser…
Incidence and survival of remnant disks around main-sequence stars
H. J. Habing, C. Dominik, M. Jourdain de Muizon +8
We present photometric ISO 60 and 170um measurements, complemented by some IRAS data at 60um, of a sample of 84 nearby main-sequence stars of spectral class A, F, G and K in order…

B. O'Halloran, L. Metcalfe, M. Delaney +5
The interacting system Arp 284 consisting of the Wolf-Rayet galaxy NGC 7714 and its irregular companion NGC 7715 was observed using the Infrared Space Observatory. Deconvolved ISOC…
ISO observations of a sample of 60 micron peaker galaxies
R. J. Laureijs, D. Watson, L. Metcalfe +9
The sample of IRAS galaxies with spectral energy distributions that peak near 60 microns are called Sixty Micron Peakers (SMPs or 60PKs). Their generally peculiar and amorphous mor…
