MAXI monitoring of blazars and blackhole binaries

TL;DR

MAXI has been monitoring the entire sky since 2009, detecting X-ray flaring activities in blazars and black hole binaries, revealing correlations between X-ray states and gamma-ray emissions.

Contribution

This paper reports new detections of X-ray flares from specific blazars and black hole binaries using MAXI, providing valuable data on their activity and state transitions.

Findings

Detection of new X-ray flares from blazars MAXI J1930+093 and 2MAXI J0243-582.

Correlation between gamma-ray emission and X-ray state transitions in black hole binaries.

Compilation of light curves and notable events for multiple sources.

Abstract

Since August 2009, MAXI experiment on the ISS has been performing all-sky X-ray monitoring. With MAXI, we detected flaring activities of some blazers, including Mrk 421, Mrk 501, and 3C 273. Recently, new X-ray flaring activities were detected from two blazers, MAXI J1930+093 = 2FGL J1931.1+0938 (Atel#5943) and 2MAXI J0243-582 = BZB J0244-5819 (Atel#6012). The MAXI monitoring also covers black hole binaries, including Cyg X-1 and Cyg X-3 which emit GeV gamma-rays. Their gamma-ray emission was found to coincide with their X-ray state transitions. We present light curves and outstanding events of these sources.
