Magnetic Fields in Molecular Clouds-Observation and Interpretation

期刊: GALAXIES, 2021; 9 (2)

The Zeeman effect and dust grain alignment are two major methods for probing magnetic fields (B-fields) in molecular clouds, largely motivated by the ......

Constraints on Lorentz Invariance Violation with Multiwavelength Polarized Astrophysical Sources

期刊: GALAXIES, 2021; 9 (2)

Possible violations of Lorentz invariance (LIV) can produce vacuum birefringence, which results in a frequency-dependent rotation of the polarization ......

Geodesic Circular Orbits Sharing the Same Orbital Frequencies in the Black String Spacetime

期刊: GALAXIES, 2021; 9 (2)

We consider isofrequency pairing of geodesic orbits that share the same three orbital frequencies associated with Omega((r) over cap), Omega((phi) ove......

Signatures of Lorentz Violation in Continuous Gravitational-Wave Spectra of Ellipsoidal Neutron Stars

期刊: GALAXIES, 2021; 9 (1)

We studied the effects of the Lorentz invariance violation on the rotation of neutron stars (NSs) in the minimal gravitational Standard-Model Extensio......

Radio Constraints of Dark Matter: A Review and Some Future Perspectives

期刊: GALAXIES, 2021; 9 (1)

In the past few decades, many studies have analyzed the data of gamma-rays, X-rays, radio waves, electrons, positrons, anti-protons, and neutrinos to ......

A Statistical Estimation of the Occurrence of Extraterrestrial Intelligence in the Milky Way Galaxy

期刊: GALAXIES, 2021; 9 (1)

In the field of astrobiology, the precise location, prevalence, and age of potential extraterrestrial intelligence (ETI) have not been explicitly expl......

Powerful Jets from Radiatively Efficient Disks, a Decades-Old Unresolved Problem in High Energy Astrophysics

期刊: GALAXIES, 2021; 9 (1)

The discovery of 3C 273 in 1963, and the emergence of the Kerr solution shortly thereafter, precipitated the current era in astrophysics focused on us......
