THE INTRINSIC PROPERTIES OF SDSS GALAXIES [PDF]
The Astrophysical Journal, 2009 The observed properties of galaxies vary with inclination; for most applications we would rather have properties that are independent of inclination, intrinsic properties. One way to determine inclination corrections is to consider a large sample of galaxies, study how the observed properties of these galaxies depend on inclination and then remove this

A Survey of Galaxy Pairs in the SDSS Photometric Images based on Faster-RCNN
The Astronomical JournalGalaxy pairs hold significant importance in understanding the evolution of galaxies, and the extensive search for a large sample of galaxy pairs is meaningful.

Comparing Globular Cluster System Properties with Host Galaxy Environment
The Astrophysical Journal, 2023 We present Hubble Space Telescope photometry in the optical (F475X) and near-infrared (F110W) bands of the globular cluster (GC) systems of the inner halos of a sample of 15 massive elliptical galaxies.

Properties of Galaxies with Peculiar Nuclei [PDF]
Publications of the Astronomical Society of the Pacific, 1967 In a former note (Sersic and Pastoriza 1965) we published the results of a survey of bright southern galaxies which were inspected for peculiarities in their nuclei. Although the sample was small ( 35 galaxies) it suggested a relationship between the existence of a bar and the presence of abnormal features in their nuclei.

On the Effects of Parameters on Galaxy Properties in CAMELS and the Predictability of Ωm
The Astrophysical JournalRecent analyses of cosmological hydrodynamic simulations from CAMELS have shown that machine learning models can predict the parameter describing the total matter content of the universe, Ω _m , from the features of a single galaxy.

Photometric Properties of Box-Shaped Galaxies [PDF]
Symposium - International Astronomical Union, 1993 A bulge/disk decomposition technique using a thin and a thick disk model is applied to a sample of 11 objects. In the thick disk modeling, the profiles are obtained in five differents radial directions. The results show that the model of thick disk is more realist.

The Astrophysical JournalThe spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional methods, including both parametric and nonparametric approaches, often fail to ...

Constraints on Assembly Bias from Galaxy Clustering
, 2016 We constrain the newly-introduced decorated Halo Occupation Distribution (HOD) model using SDSS DR7 measurements of projected galaxy clustering or r-band luminosity threshold samples.

Statistical properties of galaxy distributions [PDF]
Nonlinear Processes in Geophysics, 1996 The recent availability of complete three dimensional samples of galaxies and clusters permits a direct study of their spatial properties. We present a brief review of galaxy correlations based on the methods modern statistical Physics.
