We present the Spitzer MIPS 24 µm source counts in the Extragalactic First Look Survey main, verification and ELAIS-N1 fields. Spitzer's increased sensitivity and efficiency in large areal coverage over previous infrared telescopes, coupled with the enhanced sensitivity of the 24 µm band to sources at intermediate redshift, dramatically improve the quality… (More)
We present a new method of estimating noise variance. The method is applicable for ID and 2D signal processing. The essence of this method is estimation of the scatter of normally distributed data with high level of outliers. The method is applicable to data with the majority of the data points having no signal present. The method is based on the shortest… (More)
We use Bayes' probability theorem to analyze many-pole fits of hadron propagators. An alternative method of estimating values and uncertainties of the fit parameters is offered, which has certain advantages over the conventional methods. The probability distribution of the parameters of a fit is calculated. The relative probability of various models is… (More)
We use Spitzer Space Telescope observations from the Spitzer Survey of the Small Magellanic Cloud (S 3 MC) to study the young stellar content of N66, the largest and brightest H II region in the SMC. In addition to large numbers of normal stars, we detect a significant population of bright, red in-frared sources that we identify as likely to be young… (More)
We present the reduction of the 24µm data obtained during the first cosmological survey performed by the Spitzer Space Telescope (First Look Survey, FLS). Images of a region of sky at moderately high galactic latitude (l=88.3, b=+34.9) were obtained on 9-11 December 2003.
