Photometric Redshifts with Surface Brightness Priors [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2007
We use galaxy surface brightness as prior information to improve photometric redshift (photo-z) estimation. We apply our template-based photo-z method to imaging data from the ground-based VVDS survey and the space-based GOODS field from HST, and use ...

On the determinants of surface brightness [PDF]

open access: yesPsychonomic Bulletin and Review, 2003
The brightness of an achromatic surface with luminance S on an achromatic background with luminance B varies with S, with B, and with the luminance step deltaL at the border of the surface. In agreement with previous findings indicating that the visual system can perform as a photometer, the results of the two experiments reported here show that S and ...

The properties of Low Surface Brightness galaxies [PDF]

open access: yesAstrophysics and Space Science, 2002
A description is given of the samples of Low Surface Brightness galaxies (LSBs) used for comparison with models of their chemical and spectro-photometric evolution (Boissier et al., this Volume).

On the formation of Ganymede's surface brightness asymmetries: Kinetic simulations of Ganymede's magnetosphere

open access: yesGeophysical Research Letters, 2016
Ganymede possesses strong surface brightness asymmetries both between its polar cap and equatorial regions and between its leading and trailing hemispheres.

Surface Brightness Plateau in S4G Galaxies

open access: yesGalaxies, 2020
Using 3.6-μm data from 2112 galaxies, we show that, contrary to widely held expectations of a continuous steep decline, radial surface brightness profiles of galaxies tend to flatten and form extended plateaus beyond 27–28 magAB/arcsec2.

H i Observations of Giant Low Surface Brightness Galaxies

open access: greenThe Astrophysical Journal
Giant low surface brightness (gLSB) galaxies are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses, which can reach 10 ^12 M _⊙ .

The z<=0.1 Surface Brightness Distribution [PDF]

open access: yesAstronomy & Astrophysics, 2003
The surface brightness distribution (SBD) function describes the number density of galaxies as measured against their central surface brightness. Because detecting galaxies with low central surface brightnesses is both time-consuming and complicated ...

Found: High Surface Brightness Compact Galaxies [PDF]

open access: yesInternational Astronomical Union Colloquium, 1998
We are using the 2dF spectrograph to make a survey of all objects (`stars' and `galaxies') in a 12 sq.deg region towards the Fornax cluster. We have discovered a population of compact emission-line galaxies unresolved on photographic sky survey plates ...

Forecasting Constraints from Surface Brightness Fluctuations in Galaxy Clusters [PDF]

open access: greenThe Astrophysical Journal
Studies of surface brightness (SB) fluctuations in the intracluster medium present an indirect estimate of turbulent pressure support and associated Mach numbers.
