The Fermi LAT table of monitored sources provides daily and weekly fluxes for sources of interest as described in <a...

This is the third update to the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi Large Area Telescope (LAT). This version (4LAC-DR3) derives from the third...

This table lists all of the triggers observed by one or more of the 14 GBM detectors (12 NaI and 2 BGO). Note that there are two Browse catalogs resulting from GBM triggers. All...

Based on the collected multiwavelength data, namely in the radio (NVSS, FIRST, RATAN-600), IR (WISE), optical (Pan-STARRS), UV (GALEX), and X-ray (ROSAT, Swift-XRT) ranges, we...

The coeval AGN and galaxy evolution and the observed local relations between super-massive black holes (SMBHs) and galaxy properties suggest some connection or feedback between...

Compton Gamma-Ray Observatory (CGRO) BATSE Earth-occultation data have been used by Malizia et al. (1999, ApJ, 519, 637) to search for emission in the 20-100 keV band from all...

This table comprises CAIXA, the "Catalog of AGN In the XMM-Newton Archive". It consists of all the radio-quiet, X-ray unobscured (N_H < 2 x...

The BATSE Trigger data (each trigger is specified by a unique trigger number) are a set of triggered events that are classified as either a (solar) flare, (gamma-ray) burst,...

The CGRO/BATSE Complete Spectral Catalog of Bright Gamma-Ray Bursts (GRBs) contains the results of a systematic spectral analysis of 350 bright GRBs observed with the Burst and...

This database table comprises the gamma-ray bursts detected by the BATSE instrument on the Compton Gamma-Ray Observatory (CGRO). It includes the gamma-ray bursts from the BATSE...

This database table comprises the 4th BATSE Gamma-Ray Burst Catalog, hereafter referred to as 4B. It specifies the locations and times for 1637 triggered gamma-ray bursts...

The CGRO/BATSE 5B Gamma-Ray Burst Spectral Catalog contains the results of systematic spectral analyses of gamma-ray bursts (GRBs) detected with the Burst and Transient Source...

This table contains an all-sky sample of ~1.4 million active galactic nuclei (AGNs) meeting a two-color infrared photometric selection criterion for AGNs as applied to sources...

This table contains some of the results from a variability study of a sample of bright gamma-ray (30 MeV - 50 GeV) sources. This sample is an extension of the first AGILE...

Observations of the lensed quasar Q2237+0305 performed between 1995 and 1998.

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...

Blazar PG 1553+113 is thought to be a host of supermassive black hole binary system. A 2.2yr quasi-periodicity in the {gamma}-ray light curve was detected, possibly a result of...

The First Byurakan Survey (FBS) is the largest and the first systematic objective prism survey of the extragalactic sky. It covers 17,000 sq.deg. in the Northern sky together...

The LOFAR Two Meter Sky Survey LoTSS DR2 (:bibcode:2022A&A...659A...1S) obtained radio data from 27% of the northern sky between 120 and 168 MHz in the year 2014 through...
