Predicted HST FOC and broad band colours for young and intermediate Simple Stellar Populations
This paper presents theoretical HST and broad band colours from population synthesis models based on an homogeneous set of stellar evolutionary tracks as computed under canonical (no overshooting) assumptions, covering the range of cluster ages from t = 8 Myr to t = 5 Gyr for three different metallicities (Z = 0.02, 0.006, and 0.001). Statistical fluctuations in the cluster population have been...
متن کاملBroad-band colors and overall photometric properties of template galaxy models from stellar population synthesis
We present here a new set of evolutionary population synthesis models for template galaxies along the Hubble morphological sequence. The models, that account for the individual evolution of the bulge, disk, and halo components, provide basic morphological features, along with bolometric luminosity and color evolution (including Johnson/Cousins, Gunn g, r, i, and Washington C,M, T1, T2 photometr...
متن کاملBroad band infrared spectroscopy of massive young stellar objects
We present intermediate resolution 0.9–2.5μm IR spectra of 12 highly reddened stars, including some well known and some unfamiliar sources. A new technique for extracting calibration curves from standard star data is employed, and is found to be very successful. The reddening to each object is fully discussed and is calculated from both the continua (which was split into shortand long-wavelengt...
متن کاملRecovering Stellar Population Properties and Redshifts from Broad-band Photometry of Simulated Galaxies: Lessons for Sed Modeling
We present a detailed analysis of our ability to determine stellar masses, ages, reddening and extinction values, and star formation rates of high-redshift galaxies by modeling broad-band SEDs with stellar population synthesis. In order to do so, we computed synthetic optical-to-NIR SEDs for model galaxies taken from hydrodynamical merger simulations placed at redshifts 1.5 ≤ z ≤ 2.9. Viewed un...
متن کاملBroad-Band Difference Interferometer
Thanks to researches and the development of integrated optics devices for optical applications in the telecommunications, relatively cheap sources and detectors of optical radiation that can be used in the design of planar optical sensors [1, 2]. One of the commonly used sensor systems is the differential interferometer, based on planar waveguides [3]. In the analyzed system propagates a mode f...
