Galaxy Zoo: Passive Red Spirals [PDF]

, 2010
We study the spectroscopic properties and environments of red spiral galaxies found by the Galaxy Zoo project. By carefully selecting face-on, disk dominated spirals we construct a sample of truly passive disks (not dust reddened, nor dominated by old ...

Using non-destructive sampling to evaluate the population genomic status of captive Brown Eared Pheasants

Avian Research, 2023
Evaluating the genetic status of threatened species is an essential task in conservation genetics. However, the genetic status of threatened species has been mostly evaluated through techniques that fail to estimate genetic diversity at the whole genomic

Galaxy Zoo:reproducing galaxy morphologies via machine learning [PDF]

, 2009
We present morphological classifications obtained using machine learning for objects in SDSS DR6 that have been classified by Galaxy Zoo into three classes, namely early types, spirals and point sources/artifacts.
