Supernova remnants are beautiful astronomical objects that are also of high scientific interest, because they provide insights into supernova explosion mechanisms, and because they are the likely sources of Galactic cosmic rays. X-ray observations are an important means to study these objects. And in particular the advances made in X-ray imaging spectroscopy over the last two decades has greatly increased our knowledge about supernova remnants. It has made it possible to map the products of…

Abstract Supernova remnants have long been considered to be the dominant sources of Galactic cosmic rays. For a long time the prime evidence consisted of radio synchrotron radiation from supernova
X-ray Observations of Supernova Remnants - environment study of acceleration sites
Abstract X-ray observations are one of the strong tools to study acceleration sites of cosmic rays, not only with synchrotron emission but also with thermal emission from heated plasma. Thermal
X-Ray Emission Properties of Supernova Remnants
X-ray emission from supernova remnants can be broadly divided into thermal X-ray emission from the shock-heated plasmas and in nonthermal (synchrotron) emission caused by very high-energy (10–100
Because supernova remnants are short-lived, studies of neutron star X-ray binaries within supernova remnants probe the earliest stages in the life of accreting neutron stars. However, such objects
Supernova Remnants Interacting with Molecular Clouds: X-Ray and Gamma-Ray Signatures
The giant molecular clouds (MCs) found in the Milky Way and similar galaxies play a crucial role in the evolution of these systems. The supernova explosions that mark the death of massive stars in
Supernova remnants in the very–high–energy gamma-ray domain: the role of the Cherenkov telescope array
Supernova remnants are often presented as the most probable sources of Galactic cosmic rays. This idea is supported by the accumulation of evidence that particle acceleration is happening at
Acceleration of cosmic rays and gamma-ray emission from supernova remnants in the Galaxy
Galactic cosmic rays are believed to be accelerated at supernova remnant shocks. Though very popular and robust, this conjecture still needs a conclusive proof. The strongest support to this idea is
Gamma-ray and Neutrino Signatures of Galactic Cosmic-ray Accelerators
Supernova remnants are believed to be the major contributors to the observed Galactic cosmic-ray flux, though indisputable observational pieces of evidence of such statement are still missing. A
The supernova remnant W44: Confirmations and challenges for cosmic-ray acceleration
The middle-aged supernova remnant (SNR) W44 has recently attracted attention because of its relevance regarding the origin of Galactic cosmic-rays. For the first time for a SNR, the gamma-ray
Constraining the cosmic ray spectrum in the vicinity of the supernova remnant W28: from sub-GeV to multi-TeV energies
Supernova remnants interacting with molecular clouds are ideal laboratories to study the acceleration of particles at shock waves and their transport and interactions in the surrounding interstellar


X-ray high resolution and imaging spectroscopy of supernova remnants
The launch of Chandra and XMM-Newton has led to important new findings concerning the X-ray emission from supernova remnants. These findings are a result of the high spatial resolution with which

The most relevant results on supernova remnants obtained during the first decade of Chandra and the impact that these results have had on open issues in supernova research are reviewed.
Supernova Remnants at High Energy
Many shell supernova remnants are now known to radiate synchrotron X-rays. Several objects have also been detected in TeV gamma rays. Nonthermal X-rays and gamma rays can be produced in shell
Gamma-Ray Emission from the Shell of Supernova Remnant W44 Revealed by the Fermi LAT
An image is obtained of the supernova remnant W44, which shows associated gamma-ray emissions in the order of gigaelectronvolts, conforming with models indicating local proton and nuclei acceleration, and implies that the emission is produced by particles accelerated there.
X-ray synchrotron emission from supernova remnants
Abstract X-ray synchrotron emission tells us of the highest energy reached by accelerated electrons. In a few supernova remnants (SN 1006, G347.3-0.5) this is the dominant form of X-ray radiation,
Thermal x-ray emission and cosmic ray production in young supernova remnants
We have developed a simple model to investigate the modifications of the hydrodynamics and nonequilibrium ionization X-ray emission in young supernova remnants due to nonlinear particle acceleration.
Evidence of 10-100 TeV Electrons in Supernova Remnants
Analyses of the X-ray data of the five young shell-type supernova remnants Cas A, Kepler, Tycho, SN 1006, and RCW 86 suggest that some of the X-ray emission of these sources is non-thermal. This
Supernova remnants may exhibit both thermal and nonthermal X-ray emission. In a previous study with ASCA data, we found that the middle-aged supernova remnant RCW 86 showed evidence for both
Extremely fast acceleration of cosmic rays in a supernova remnant
Broadband X-ray spectrometric measurements of RX J1713.7-3946 indicate that electron acceleration proceeds in the most effective (‘Bohm-diffusion’) regime, providing a strong argument for acceleration of protons and nuclei to energies of 1 PeV (1015 eV) and beyond in young supernova remnants.
Multiwavelength Signatures of Cosmic Ray Acceleration by Young Supernova Remnants
An overview is given of multiwavelength observations of young supernova remnants, with a focus on the observational signatures of efficient cosmic ray acceleration. Some of the effects that may be
