Space-Earth System Produces Highest-Resolution Astronomical Image
Space-Earth System Highest-Resolution Astronomical Image
2016/2/22
Using an orbiting radio-astronomy satellite combined with 15 ground-based radio telescopes, astronomers have made the highest-resolution, or most-detailed, astronomical image yet, revealing new insigh...
Effect of DEM Resolution on the Simulation of Astronomical Radiation
DEM Astronomic Radiation Resolution Sensitive Analysis
2015/12/2
The development of digital terrain analysis based on DEM is helpful for the simulation of astronomic radiation in rugged area. However the effect of DEM scale causes great uncertainty to the simulatio...
The correspondence of Giovanni Santini and Giuseppe Lorenzoni, directors of the Astronomical Observatory of Padua in the 19th century
Giovanni Santini Giuseppe Lorenzoni
2015/8/28
Giovanni Santini was appointed director of the Astronomical Observatory of Padova from 1817 to 1877. His scientific correspondence covers a period from 1807 to 1874. Most of the letters are from Itali...
Astronomical Image Representation by the Curvelet Transform
methods Data Analysis-techniques Image Processing
2015/6/17
We outline digital implementations of two newly developed multiscale representation systems, namely, the ridgelet and curvelet transforms. We apply these digital transforms to the problem of restoring...

This paper deals about astronomical orientation of Incas objects in Ollantaytambo, which is located about 35 km southeast from Machu Picchu, about 40 km northwest from Cusco, and lies in the Urubamba ...
Far-Infrared to Millimeter Astrophysical Dust Emission. II: Comparison of the Two-Level Systems (TLS) model with Astronomical Data
Far-Infrared Millimeter Astrophysical Dust Emission Comparison model Astronomical Data
2011/10/20
In a previous paper we proposed a new model for the emission by amorphous astronomical dust grains, based on solid-state physics. The model uses a description of the Disordered Charge Distribution (DC...
Understanding strong molecular hydrogen emission in astronomical environments
Understanding strong molecular hydrogen emission astronomical environments
2011/10/13
Here I describe recent studies of objects with molecular hydrogen emission that is strong relative to other spectral lines. Large telescopes and fast spectrometers have made the 2 {\mu}m window access...
3-D deconvolution of hyper-spectral astronomical data
Supernova – inverse problem – deconvolution – hyperspectral imaging
2011/10/12
In this paper we present a general forward fitting method for multichannel image restoration based on regularized chi2. We introduce separable regularizations that account for the dynamic of the model...
TESELA: a new Virtual Observatory tool to determine blank fields for astronomical observations
Observatory determine blank fields astronomical observations
2011/10/12
The observation of blank fields, regions of the sky devoid of stars down to a given threshold magnitude, constitutes one of the typical important calibration procedures required for the proper reducti...
Horizon synthesis for archaeo-astronomical purposes
Methods: numerical – General: history and philosophy of astronomy
2011/10/18
In this paper I describe a simple numerical procedure to compute synthetic horizon altitude profiles for any given site. The method makes use of a simplified model of local Earth's curvature, and it i...
