PNe using Gaia DR3 and O/H gradient
The spatial distribution of chemical elements in the Galactic disk provides key constraints on models of galaxy evolution. However, studies using planetary nebulae (PNe) as... -
NGC 346 VIHa photometry
We studied the properties of star formation and the characteristics of young stars in a quiet region located beyond the outskirts of the prominent star-forming cluster NGC 346... -
Symbiotic star candidates in inner Galactic disk
The origin of the highly ionized iron emission (FeXXV at 6.7keV) characterizing the Galactic ridge X-ray emission (GRXE) remains a fundamental puzzle in high-energy... -
CAMIRA clusters in the eFEDS field
This is the second paper in a series exploring the X-ray properties of galaxy clusters optically selected by the Subaru Hyper Suprime-Cam (HSC) survey, using data from the... -
[M/H] of K/M dwarfs in SN kinematic structures
We combine photometric metallicities with astrometry from Gaia DR3 to examine the chemodynamic structure of ~250000 K dwarfs in the solar neighbourhood (SN). In kinematics, we... -
WALLABY Hydra I cl. H I galaxy morphometrics
Galaxy morphology in atomic hydrogen (H I) and in the ultraviolet (UV) are closely linked. This has motivated their combined use to quantify morphology over the full H I disc... -
Stellar properties of Sun-like stars SDST III
The Survey for Distant Solar Twins aims to find stars very similar to the Sun at distances of 1-4kpc, several times more distant than any currently known solar twins and... -
Omega/WINGS clusters/fields galaxies
The observed properties of galaxies are strongly dependent on both their total stellar mass and their morphology. Furthermore, the environment is known to play a strong role in... -
HSC gLSB galaxies structures and SB properties
Rare giant low surface brightness galaxies (gLSBGs) act as a stress test for the current galaxy formation paradigm. To answer the question 'How rare are they?', we estimate... -
n-catpure abundances in NGC 6752
Globular clusters have been widely studied in terms of light element variations present in their different stellar populations. However, the nature of the polluter(s)... -
Remnant merger structures of ETGs with SDSS
We search for signatures of recent galaxy close interactions and mergers in a sample of 202 early-type galaxies in the local universe from the public SDSS Stripe82 deep images... -
X-ray catalog and classification of 4FGL-DR4 UGSs
Our survey of the fourth Fermi Large Area Telescope catalog (4FGL) unassociated gamma-ray source regions using the X-Ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT)... -
NESSI: resolving wide binaries in Gaia & SUPERWIDE
Stellar systems consisting of three or more stars are not an uncommon occurrence in the Galaxy. Nearly 50% of solar-type wide binaries with separations >1000AU are actually... -
MGQPC photo-z and high-probability pair catalogs
The identification of physically associated kiloparsec-scale quasar pairs is important for understanding galaxy evolution, the growth of supermassive black holes, and the... -
Data Central SSA
Spectra from surveys hosted by Data Central. Most spectra were taken with the multi-object spectroscopy facilities 2dF (Anglo-Australian Telescope) and 6dF (UK Schmidt Telescope). -
CEERS Key Paper. VIII. NIRSpec & NIRCam sp.
We use James Webb Space Telescope Near-Infrared Camera Wide Field Slitless Spectroscopy (NIRCam WFSS) and the Near-Infrared spectrograph (NIRSpec) in the Cosmic Evolution Early... -
3D kinematics in the ONC. II. Mass-dependent results
We present the kinematic analysis of 246 stars within 4' from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formation across the... -
QSOs at z~4 from Subaru/HSC wide field & BH masses
We investigate the black hole mass function (BHMF) and Eddington-ratio distribution function (ERDF) of broad-line active galactic nuclei (AGNs) at z=4, based on a sample of 52... -
Classifying intermediate-z galaxies in SDSS
We select a sample of 1437 active galactic nuclei (AGN) from the catalog of the Sloan Digital Sky Survey galaxy properties from the Portsmouth group by detection of the... -
ACO 746 analysis with Subaru & MMT spectra data
The galaxy cluster A746 (z=0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intricate...
