THE CALIBRATION OF MONOCHROMATIC FAR-INFRARED STAR FORMATION RATE INDICATORS
star formation starburst galaxies
2014/12/20
Spitzer data at 24, 70, and 160 μm and ground-based Hα images are analyzed for a sample of 189 nearby star-forming and starburst galaxies to investigate whether reliable star formation rate (SFR) indi...
IDENTIFICATION OF A COMPLETE 160 μm FLUX-LIMITED SAMPLE OF INFRARED GALAXIES IN THE ISO LOCKMAN HOLE 1 deg2 DEEP FIELDS: SOURCE PROPERTIES AND EVIDENCE FOR STRONG EVOLUTION IN THE FIR LUMINOSITY FUNCTION FOR ULIRGs
starburst-active galactic nucleus (AGN) composite AGN spectral types
2014/12/20
We have identified a complete, flux-limited (S 160>120 mJy) sample of 160 μm selected sources from Spitzer observations of the 1 deg2 Infrared Space Observatory (ISO) Deep Field region in the Lockman ...
Investigation of Herbig Ae /Be stars in the near -infrared with a long baseline interferometer
Long baseline Stars Near infrared interferometry The dust
2014/12/9
We have conducted the first systematic study of Herbig Ae/Be stars using the technique of long baseline spatial interferometry in the near-infrared, with the objective of characterizing the distributi...
A Bayesian Approach to Calibrating Period-Luminosity Relations of RR Lyrae Stars in the Mid-Infrared
statistical methods RR Lyrae distance scale
2012/2/23
A Bayesian approach to calibrating period-luminosity (PL) relations has substantial benefits over generic least-squares fits. In particular, the Bayesian approach takes into account the full prior dis...
A Mid-Infrared Indicator for Total Infrared Luminosity and Star Formation Rate of Local and High-Redshift Galaxies
Indicator Total Infrared Luminosity High-Redshift Galaxies
2011/10/9
We present a new method to use 24 micron observations to estimate the total infrared luminosity, LIR, and the star formation rate of star-forming galaxies across the redshift range 0 < z < 3. This is ...
Herschel/HerMES: The X-ray - Infrared correlation for star-forming galaxies at z~1
X-ray - Infrared correlation star-forming galaxies
2011/9/29
For the first time, we investigate the X-ray/infrared (IR) correlation for star-forming galaxies at z~1, using SPIRE submm data from the recently-launched Herschel Space Observatory and deep X-ray dat...
Mid-infrared interferometric monitoring of evolved stars - The dust shell around the Mira variable RR Aql at 13 epochs
Techniques:interferometric – Stars:AGB – Stars:atmospheres – Stars:mass loss – Stars:individual:RR Aql
2011/9/28
We obtained 13 epochs of mid-infrared interferometry with the MIDI instrument at the VLTI between April 2004 and July 2007, covering pulsation phases 0.45-0.85 within four cycles. The data are modeled...

Far Infrared Mapping of Three Galactic Star Forming Regions: W3 (OH), S209 & S187
Interstellar dust W3(OH)–S209 S187
2009/5/20
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 200m using the TIFR 100 cm
