Phoenix Spectra of Carbon Stars in the LMC
We present high-resolution, IR-spectra of Carbon stars in the LMC obtained with the Phoenix spectrometer on the Gemini South 8-meter telescope. This... -
Multi-Object Spectroscopy: Automatic Extraction and Previewing of Spectra
With multi-object spectroscopy becoming an integral part of modern astronomical instrumentation, the amount of such data in archives is bound to... -
Modeling and Simulating X-ray Spectra
X-ray spectroscopy is a powerful technique for the analysis of the energy distribution of X-rays from astrophysical sources. It allows for the study... -

On the Spectra of the Gamma-Ray Bursts
Abstract. The soft tails of gamma-ray bursts spectra obtained by different instruments are discussed. It is known that some of them have excesses... -
UPCA: Extension of PCA Analysis of Galaxy Spectra to Unfluxed Data
The Principal Component Analysis (PCA), allows to describe a spectrum with few physical significative parameters and it has demonstrated to be a... -
Gas Phase IR Spectra of Hydrogen Functionalised Pentacene
We present gas-phase infrared (IR) spectra of protonated dihydropentacene, the hydrogen functionalised form of the linear, catacondensed, polycyclic... -
Parameterisation of Galaxy Spectra in the 2dF Galaxy Redshift Survey
The 2dF Galaxy Redshift Survey has already yielded over 130,000 galaxy spectra (out of the planned 250,000). We present a method for the... -
Ultraviolet Absorption Spectra of Some Tellurite Glasses
The present chapter deals with the interaction of the UV spectra with some tellurite glasses. -
Infrared Spectra of Red Giants: Molecular and Atomic Lines
We discuss some of the most severe problems concerning the calculation of synthetic high resolution spectra of cool oxygen rich giants by studying... -
Improvements in digital meteor spectra reduction
This study addresses the complexity and importance of develo** a method of calibrating digital observations of meteor spectra with all-sky cameras....

Mass Spectra from Turbulent Fragmentation
Turbulent fragmentation determines where and when protostellar cores form, and how they contract and grow in mass from the surrounding cloud... -
Statistical Properties of Pulsars with the Gigahertz-Peaked Spectra
AbstractPulsars with the Gigahertz-Peaked Spectra (GPS) are named GPS pulsars, which means that spectra of the pulsars in the radio band turn over...

Clustering of Galaxy Spectra: An Unsupervised Approach with Fisher-EM
We present a novel approach to galaxy spectra classification using Fisher-EM, a latent subspace clustering and Gaussian mixture model based... -
Transmission Spectra of Diluted and Concentrated Magnetite Colloids in Liquid Dielectrics
Transmission spectra of colloidal solutions of magnetite nanoparticles in kerosene with various volume concentrations of the solid phase and the...

Correcting the Chromatic and Airmass Dependent Extinction for TIMMI2 Spectra
We present a method to correct the chromatic and airmass dependent extinction for N-band spectra taken with the TIMMI2 instrument at the ESO/La Silla... -
Method for Analysis of Asymmetric Spectra Based on the Information Entropy Model
AbstractThe possibility is considered of using asymmetric distributions to analyze emission/absorption spectra, which enables revealing the structure...

11 Typical Spectra of Large Systems
If a set of axioms is formulated as a basis of thermodynamics, one is usually told that entropy has to be an extensive quantity. This basically means...
