Bright galaxy number counts [PDF]

, 1995
The value of a plot of galaxy number counts per unit area of sky against magnitude as a probe of the early universe is well known, being influenced by both the curvature of expanding space and the deceleration parameter.

Flux Cube Reconstruction from Slitless Spectroscopy

The Astronomical Journal
Slitless spectroscopy enables efficient, large-area surveys without target preselection, yet it faces challenges from source blending, higher noise, and lost spatial–spectral information.

Correcting the fiber-aperture bias affecting galaxy stellar populations in the Legacy Sloan Digital Sky Survey

Astronomy & Astrophysics
Context. A detailed characterization of stellar population properties is crucial for understanding galaxy evolution. Their inference for statistically representative samples requires deep multi-object spectroscopy, typically obtained with fiber-fed ...

Towards AMR Simulations of Galaxy Formation [PDF]

, 2010
Numerical simulations present a fundamental building block of our modern theoretical understanding of the Universe. As such the work in this thesis is primarily concerned with understanding fundamental differences that lie between the different ...

Broad line emission from iron K- and L-shell transitions in the active galaxy 1H 0707-495

, 2009
Since the 1995 discovery of the broad iron K-line emission from the Seyfert galaxy MCG-6-30-15 (ref. 1), broad iron K lines have been found in emission from several other Seyfert galaxies, from accreting stellar-mass black holes and even from accreting ...

Electron Shot Noise on a Current Biased Antenna

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The Parker Solar Probe (PSP) Fields Experiment (FIELDS) uses Radio Frequency Spectrometer (RFS) data and Quasi‐Thermal Noise Spectroscopy (QTN) to determine the temperature and density of electrons in the heliosphere. The FIELDS antennas typically operate with a negative bias current.

IRAS LRS spectroscopy of galaxies

The Astronomical Journal, 1992
The study presents IRAS LRS data for 350 galaxies with pointlike IRAS sources having either S(12) or S(25) not less than 1.5 Jy. Techniques are presented which form the mean of an ensemble of LRS spectra, ll of which are only of low signal-to-noise ratio, by quantitative evaluation of the significance of the individual spectra for each object rather ...

A study of radio continuum emission of the Milky Way Galaxy [PDF]

, 1996
The synchrotron emissivity distribution of the Milky Way Galaxy has been modelled from the 408 MHz allsky survey of Haslam et al.(1982) after separation of its thermal component with the help of IRAS 60 micron emission(Broadbent et al 1989).
