Special Issue Information
Dear Colleagues,
The present issue presents a comprehensive multi-wavelength analysis of the compact astrophysical sources of high energy, such as Kilonova, gamma-ray bursts, and double O-Ne-Mg white dwarf mergers that can be followed by a supernova-type Ia.
Newly formed black holes of stellar mass launch collimated outflows (jets) of ionized matter that approach the speed of light. The power of these outflows prompt brief and intense flashes of γ-rays, known as γ-ray bursts (GRBs), followed by a longer-lived afterglow radiation that is detected across the electromagnetic spectrum.
The nature of the GRB central engines, as well as the mechanism by which these jets are launched and collimated, remains poorly understood and requires observations and analyses that include the subjects of electromagnetics and gravitational waves.
This multi-wavelength analysis of the gamma-ray bursts specifically focuses on the early stages of their evolution and includes the data from gamma-ray orbital observatories (such as Swift, Fermi, Integral, Lomonosov, and Konus-Wind).
On of the crucial methods to understand the gamma-ray bursts from the perspective of astrophysics is the discovery of prompt optical emissions from GRBs, the detection of the gravitational wave range (GW170817/GRB170817A), and the first detection of polarized prompt optical emissions (GRB 160625B).
It is well known that short gamma-ray bursts are the result of merging compact objects, for example, neutron stars. The first calculation of the neutron star (NS) merger rate was obtained in 1987, which was confirmed on 17 August 2017 using the Kilonova detection method with LIGO/Virgo detectors, with gamma rays (discovered by Fermi) and independently discovered in optics with 1M2H Swope, DLT40, VISTA, MASTER, DECam, and Las Cumberes. Short gamma-ray bursts can also be the result of the pair merging of a black hole and a neutron star (BH + NS). Long gamma-ray bursts are associated with the core collapse of a rapidly rotating massive star.
A combined study of the prompt and afterglow properties, including the study of the multi-wavelength light curves and broadband spectra, allows us to select the optimal models to explain emission components, including a bright reverse shock emission, visible at early times in the optical and X-rays and, later, in the radio band, and a forward shock component dominating at later times and with similarities in lower radio frequencies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
