High-velocity X-ray sources
We perform a comprehensive search for high-velocity X-ray sources with large X-ray/optical flux ratios (F_X_/F_G_), identifying candidates for interacting black hole or neutron... -
Spectral galaxy pairs from SDSS DR9
Spectral galaxy pairs (hereafter as SGPs) are composite galaxy spectra that contain two independent redshift systems. These spectra are useful for studying the dust properties... -
GX 339-4 radio/X-ray flux correlation
The existing radio and X-ray flux correlation for Galactic black holes in the hard and quiescent states relies on a sample which is mostly dominated by two sources (GX 339-4 and... -
Discovery of bright z~=7 LBGs in Euclid COSMOS
We present a search for z ~= 7 Lyman-break galaxies using the 1.72 deg^2^ near-infrared UltraVISTA survey in the COSMOS field, reaching 5 {sigma} depths in Y of 26.2. We... -
5 AGNs soft excess and X-ray continuum
Changing-state active galactic nuclei (CSAGNs) exhibit rapid variability, with mass accretion rates that can change by several orders of magnitude in a few years. This provides... -
eJWST AGN observation catalogue
The European Archive of the James Webb Space Telescope (eJWST) provides access to all data collected by The James Webb Space Telescope (JWST). JWST's capabilities span from... -
X-ray active galactic nucleus at z~0.4
We present an analysis of the X-ray active galactic nucleus (AGN) population in a sample of seven massive galaxy clusters in the redshift range 0.35<z<0.45. We utilize... -
ACT_Planck DR4 f090 survey collection
The Atacama Cosmology Telescope (ACT) is a six-meter diameter telescope on Cerro Toco in the Atacama Desert of northern Chile (image above by Jon Ward). It is designed to make... -
Spitzer IRS Enhanced Products
The Enhanced Products consist of two elements: (1) A collection of 16,986 low-resolution, merged spectra (2) A Catalog of extracted source positions, synthetic photometry in... -
POPSTAR with Kroupa IMF
PopStar Evolutionary synthesis models. Using IMF from Kroupa (2002). This grid of Single Stellar Populations covers a wide range in both, age and metallicity. The models use the... -
PlanckRevised CO21 survey collection
The Planck space mission has observed the first three rotational lines of emission of Galactic carbon monoxide (CO). Those maps, however, are either noisy or contaminated by... -

The Atacama Cosmology Telescope (ACT) is a six-meter diameter telescope on Cerro Toco in the Atacama Desert of northern Chile (image above by Jon Ward). It is designed to make... -
ACT_Planck DR4 f150 survey collection
The Atacama Cosmology Telescope (ACT) is a six-meter diameter telescope on Cerro Toco in the Atacama Desert of northern Chile (image above by Jon Ward). It is designed to make... -
PLANCK R2 LFI color composition 30-44-70 GHz survey collection
The Planck mission will collect and characterise radiation from the Cosmic Microwave Background (CMB) using sensitive radio receivers operating at extremely low temperatures.... -
ACT-PLANCK DR4DR6 Color CMB survey collection
This is an unpolarized map with three components corresponding to our f090, f150 and f220 bands which are broad bands with center frequency roughly at 95 GHz, 150 GHz and 220... -
Maidanak Observatory Lens Images
Reduced frames of lensed quasar observations from Maidanak Observatory. See the referenceURL for details on the reduction procedure and calibration data. -
1BIGB: First Brazil-ICRANet Gamma-Ray Blazar Catalogue
This catalog presents the 1-100 GeV spectral energy distribution (SED) for a population of 148 high-synchrotron-peaked blazars (HSPs) recently detected with Fermi-LAT as part of... -
Apache Point observations of lensed quasars
Observations of the lensed quasar Q2237+0305 performed between 1995 and 1998. -
zCosmos Bright Spectroscopic Observations DR2
The zCOSMOS redshift survey used 600h on the VIMOS spectrograph spread over five observing seasons (2005-2009) to obtain spectra of about 20,000 galaxies selected to have Iab...
