As smaller analogues of active galactic nuclei, X-ray binaries (XRBs) are also capable of launching jets that accelerate particles to high energies. In this work, we re-examine XRB jets as potential sources of high-energy cosmic rays (CRs) and explore whether they could provide a significant second Galactic component to the CR spectrum. In the most intriguing scenario, XRB-CRs could dominate the observed spectrum above the so-called knee feature at ∼3 × 1015 eV, offering an explanation for…

X-ray binaries (XRBs) are binary systems with an accreting compact object. They have long been suggested to be possible galactic cosmic ray (CR) accelerators. In such models, the protons accelerated…

Particle acceleration in radio galaxies with flickering jets: GeV electrons to ultrahigh energy cosmic rays

Variability is a general property of accretion discs and their associated jets. We introduce a semi-analytical model for particle acceleration and radio jet/lobe evolution and explore the effect of…

Deciphering the Origin of the GeV–TeV Gamma-Ray Emission from SS 433

We investigate hadronic and leptonic scenarios for the GeV–TeV gamma-ray emission from jets of the microquasar SS 433. The emission region of the TeV photons coincides with the X-ray knots, where…

A new lepto-hadronic model applied to the first simultaneous multiwavelength data set for Cygnus X–1

Cygnus X–1 is the first Galactic source confirmed to host an accreting black hole. It has been detected across the entire electromagnetic spectrum from radio to GeV gamma-rays. The source’s radio…

Magnetically Arrested Disks in Quiescent Black Hole Binaries: Formation Scenario, Observable Signatures, and Potential PeVatrons

We propose magnetically arrested disks (MADs) in quiescent (low-luminosity) black hole (BH) binaries as the origin of multiwavelength emission, and argue that this class of sources can dominate the…

Energy estimation of high-energy particles associated with the SS 433/W 50 system through radio observation at 1.4 GHz

The radio nebula W 50 is a unique object interacting with the jets of the microquasar SS 433. The SS 433/W 50 system is a good target for investigating the energy of cosmic-ray particles…

Cosmic-ray production from neutron escape in microquasar jets

Context. The origin of Galactic cosmic rays remains a matter of debate, but supernova remnants are commonly considered to be the main place where high-energy cosmic rays are accelerated.…

Continuous Jets and Backflow Models for the Formation of W50/SS 433 in Magnetohydrodynamics Simulations

The formation mechanism of the W50/SS 433 complex has long been a mystery. We propose a new scenario in which the SS 433 jets themselves form the W50/SS 433 system. We carry out magnetohydrodynamics…

Discovery of very-high-energy γ-rays from the Galactic Centre ridge

The source of Galactic cosmic rays (with energies up to 1015 eV) remains unclear, although it is widely believed that they originate in the shock waves of expanding supernova remnants. At present the…

Iron Emission Lines from Extended X-ray Jets in SS 433: Reheating of Atomic Nuclei

TLDR
These observations reveal evidence for a hot continuum and Doppler-shifted iron emission lines from spatially resolved regions and in situ reheating of the baryonic component of the jets takes place in a flow that moves with relativistic bulk velocity even more than 100 days after launch from the binary core.

DETECTION OF PERSISTENT GAMMA-RAY EMISSION TOWARD SS433/W50

The microquasar SS433 features the most energetic jets known in our Galaxy. A large fraction of the jet kinetic power is delivered to the surrounding W50 nebula at the jet termination shock, from…

Extreme particle acceleration in the microquasar Cygnus X-3

TLDR
There is a clear pattern of temporal correlations between the γ-ray flares and transitional spectral states of the radio-frequency and X-ray emission, and particle acceleration occurred a few days before radio-jet ejections for two of the four flares, meaning that the process of jet formation implies the production of very energetic particles.

Energization of interstellar media and cosmic ray production by jets from X-ray binaries

Drawing on recent estimates of the power of jets from X-ray binary systems as a function of X-ray luminosity, combined with improved estimates of the relevant log(N )‐log(L X) luminosity functions,…

Cosmic rays from microquasars: a narrow component to the CR spectrum?

We propose that relativistic Galactic jets like those observed in GRS 1915+105 and GRO J1655-40 may produce a small but measurable contribution to the cosmic ray (CR) spectrum. If these jets contain…

A large light-mass component of cosmic rays at 1017–1017.5 electronvolts from radio observations

TLDR
Radio measurements of Xmax with a mean uncertainty of 16 grams per square centimetre for air showers initiated by cosmic rays with energies of 1017–1017.5 electronvolts enable us to determine the mass spectrum of the cosmic rays: a mixed composition, with a light-mass fraction (protons and helium nuclei) of about 80 per cent.

Joint Constraints on Galactic Diffuse Neutrino Emission from the ANTARES and IceCube Neutrino Telescopes

The existence of diffuse Galactic neutrino production is expected from cosmic-ray interactions with Galactic gas and radiation fields. Thus, neutrinos are a unique messenger offering the opportunity…

FADING HARD X-RAY EMISSION FROM THE GALACTIC CENTER MOLECULAR CLOUD Sgr B2

TLDR
The observation of a clear decay of the hard X-ray emission from the molecular cloud Sgr B2 during the past seven years is reported, thanks to more than 20 Ms of INTEGRAL exposure, and it is found that the period of intense activity of Sgr A* ended between 75 and 155 years ago.

Diffusive shock acceleration at the outer front of expanding supernova remnants has provided by far the most popular model for the origin of galactic cosmic rays, and has been the subject of…
