We investigate the variability timescales in the jet of M87 with two goals. The first is to use the rise times and decay times in the radio, ultraviolet, and X-ray light curves of HST-1 to constrain the source size and the energy loss mechanisms affecting the relativistic electron distributions. HST-1 is the first jet knot clearly resolved from the nuclear emission by Chandra and is the site of the huge flare of 2005. We find clear evidence for a frequency-dependent decrease in the synchrotron… 

The core-like nature of HST-1 in the M87 jet

We investigate the total flux density, spectral, polarization and Faraday rotation variability of HST-1 in the M87 jet during the outburst from 2003 to 2007 through multi-epoch Very Large Array

The jet in M87 from e-EVN observations

Abstract One of the most intriguing open questions of today's astrophysics is the jet physical properties and the location and the mechanisms for the production of MeV, GeV, and TeV gamma-rays in AGN

Energy distribution of relativistic electrons in the kiloparsec scale jet of M 87 with Chandra

The X-ray emission from the jets in active galactic nuclei (AGN) carries important information on the distributions of relativistic electrons and magnetic fields on large scales. We reanalysed

Probing the inner jet of M87; from the jet base to HST-1

The giant radio galaxy M87 accompanies one of the nearest Active-Galactic-Nuclei jets showing the intense radiation through radio to TeV gamma-ray. Its proximity and the large mass of the central

VLBI OBSERVATIONS OF THE JET IN M 87 DURING THE VERY HIGH ENERGY γ-RAY FLARE IN 2010 APRIL

We report on the detailed radio status of the M 87 jet during the very high energy (VHE) γ-ray flaring event in 2010 April, obtained from high-resolution, multi-frequency, phase-referencing Very Long

OPTICAL POLARIZATION AND SPECTRAL VARIABILITY IN THE M87 JET

During the last decade, M87's jet has been the site of an extraordinary variability event, with one knot (HST-1) increasing by over a factor 100 in brightness. Variability has also been seen on

Fast TeV variability from misaligned minijets in the jet of M87

The jet of the radio galaxy M87 is misaligned, resulting in a Doppler factor δ~1 for emission of plasma moving parallel to the jet. This makes the observed fast TeV flares on time-scales of t v ~ 5 R

Nonthermal processes of fast outflows from astrophysical objects

Outflows are ubiquitous phenomena in the universe. They have been widely observed in both Galactic and extragalactic objects. In this thesis, we analyze three individual sources. Firstly, we

AN EXPERIMENT TO LOCATE THE SITE OF TeV FLARING IN M87

We describe a Chandra X-ray target-of-opportunity project designed to isolate the site of TeV flaring in the radio galaxy M87. To date, we have triggered the Chandra observations only once (2010

Features of Structure and Absorption in the Jet-Launching Region of M87

M87 is one of the best available source for studying the AGN jet-launching region. To enrich our knowledge of this region, with quasi-simultaneous observations using VLBA at 22, 43 and 86 GHz, we

Flaring X-Ray Emission from HST-1, a Knot in the M87 Jet

We present Chandra X-ray monitoring of the M87 jet in 2002, which shows that the intensity of HST-1, an optical knot 0.″8 from the core, increased by a factor of 2 in 116 days and a factor of 4 in 2

Month-Timescale Optical Variability in the M87 Jet

A previously inconspicuous knot in the M87 jet has undergone a dramatic outburst and now exceeds the nucleus in optical and X-ray luminosity. Monitoring of M87 with the Hubble Space Telescope and

Is the Core of M87 the Source of Its TeV Emission? Implications for Unified Schemes

M87 has recently been shown to be a TeV source that is likely to be variable. Based on this and on contemporaneous optical and X-ray monitoring, we argue that the source of the TeV emission is the

The Outburst of HST-1 in the M87 Jet

The X-ray intensity of knot HST-1, 0.″85 from the nucleus of the radio galaxy M87, has increased by more than a factor of 50 during the last 5 yr. The optical increase is similar, and our more

Superluminal motion is a common feature of radio jets in powerful γ-ray-emitting active galactic nuclei. Conventionally, the variable emission is assumed to originate near the central supermassive
