Radio-far-infrared Correlation and Cosmic Ray Electrons in Starburst Galaxies and Ultra Luminous Infrared Galaxies
T. N. Rengarajan
The ubiquitous and tight correlation between the radio continuum emission and the far-infrared emission is also found to hold true for starburst galaxies and Ultra Luminous Infrare…
Wide-Area Mapping of 155 Micron Continuum Emission from the Orion Molecular Cloud Complex
S. Arimura, H. Shibai, T. Teshima +9
We present the results of a wide-area mapping of the far-infrared continuum emission toward the Orion complex by using a Japanese balloon-borne telescope. The 155-um continuum emis…
History of Star Formation Rate and Luminosity Density of Galaxies
T. N. Rengarajan, Y. D. Mayya
We have computed the time evolution of bolometric, far-infrared, Halpha line, ultraviolet (both intrinsic and escaping the star forming region) and the nonthermal radio continuum l…
Mapping of Large Scale 158 micron [CII] Line Emission: Orion A
B. Mookerjea, S. K. Ghosh, H. Kaneda +5
We present the first results of an observational programme undertaken to map the fine structure line emission of singly ionized carbon ([CII] 157.7409 micron) over extended regions…
Far infrared mapping of three Galactic star forming regions : W3(OH), S 209 & S 187
S. K. Ghosh, B. Mookerjea, T. N. Rengarajan +2
Three Galactic star forming regions associated with W3(OH), S209 and S187 have been simultaneously mapped in two trans-IRAS far infrared (FIR) bands centered at ~ 140 and 200 micro…
Absorption Measurement of Hydrogen Molecules in the Early Universe
Hiroshi Shibai, Tsutomu T. Takeuchi, T. N. Rengarajan +1
We investigate the observability of hydrogen molecules in absorption. The absorption efficiency of the hydrogen molecules become comparable with or larger than that of the dust gra…
The Radio-to-Submillimeter Flux Density Ratio of Galaxies as a Measure of Redshift
T. N. Rengarajan, Tsutomu T. Takeuchi
We re-examine the technique of determining the redshifts of galaxies from the ratio of the submillimeter-to-radio continuum flux densities based on a recently published catalog of…
Study of star formation in RCW 106 using far infrared observations
A. D. Karnik, S. K. Ghosh, T. N. Rengarajan +1
High resolution far-infrared observations of a large area of the star forming complex RCW 106 obtained using the TIFR 1-metre balloon-borne telescope are presented. Intensity maps…
Massive and luminous YSO IRAS 05361+3539 and its environment. A study of star formation in the parent cloud - I
A. Chakraborty, D. K. Ojha, B. G. Anandarao +1
Near-infrared photometry and narrow/broad-band imaging of the massive and luminous young stellar object IRAS 05361+3539 are presented. Imaging observations were made at Mt. Abu whi…
Far infrared observations of the southern Galactic star forming complex around IRAS 09002-4732
S. K. Ghosh, B. Mookerjea, T. N. Rengarajan +2
The Galactic star forming region in the southern sky, associated with IRAS 09002-4732 has been mapped simultaneously in two far infrared bands (148 & 209 um), with ~ 1' angular res…
Distribution of Cold dust in Orion A and B
B. Mookerjea, S. K. Ghosh, T. N. Rengarajan +2
Large scale far-infrared (FIR) observations of the Orion complex at 205 and 138 micron are presented with an aim of studying the distribution of cold (< 25 K) dust. The maps in the…

B. Mookerjea, S. K. Ghosh, T. N. Rengarajan +2
High angular resolution far-infrared observations at 143 & 185 \micron, using the TIFR 1-m balloon borne telescope, are presented for two Galactic star forming complexes associated…
Far Infrared Observations of the Galactic Star Forming Regions associated with IRAS 00338+6312 & RAFGL 5111
B. Mookerjea, S. K. Ghosh, A. D. Karnik +3
Two Galactic star forming regions, one in a very early phase of evolution and another evolved one, associated with the IRAS sources 00338+6312 and 03595+5110 (RAFGL 5111) respectiv…
Spatial distribution of Far infrared emission in spiral galaxies II. Heating sources and gas-to-dust ratio
Y. D. Mayya, T. N. Rengarajan
We study the radial distribution of the temperature of the warm dust and gas-to-dust mass ratios in a sample of 22 spiral galaxies. The heating capabilities of the diffuse interste…
Spatial distribution of far infrared emission in spiral galaxies I. Relation with radio continuum emission
Y. D. Mayya, T. N. Rengarajan
We use high resolution IRAS and 20 cm radio continuum (RC) images of a sample of 22 spiral galaxies to study the correlation between the far infra-red (FIR) and RC emissions within…
