A Close Binary Supermassive Black Hole Model for the Galaxy 3C 273.
Publication Type: Academic Journal
Source(s): Galaxies (2075-4434). Oct2023, Vol. 11 Issue 5, p96. 13p.
Abstract: The data from the last 60 years on the programs of long-term multi-frequency monitoring of active galactic nucleus (AGN) 3C 273 were analyzed. A model is proposed for finding the parameters of close binary systems (CBSs) from supermassive black holes (...
Nothing into Something and Vice Versa: A Cosmological Scenario.
Publication Type: Academic Journal
Source(s): Universe (2218-1997). Oct2023, Vol. 9 Issue 10, p445. 7p.
Abstract: In the almost empty universe (with almost no matter in it), stochastic gravitational waves (SGW) of finite amplitude produce a de Sitter regime as a solution, which is invariant with respect to the Wick rotation. Asymptotically, super horizon SGWs do n...
AI in Gravitational Wave Analysis, an Overview.
Publication Type: Academic Journal
Source(s): Applied Sciences (2076-3417). Sep2023, Vol. 13 Issue 17, p9886. 13p.
Abstract: Gravitational wave research presents a range of intriguing challenges, each of which has driven significant progress in the field. Key research problems include glitch classification, glitch cancellation, gravitational wave denoising, binary black hole...
BEYOND GEOMETRIC OPTICS LIMIT OF GRAVITATIONAL WAVE LENSING IN PALATINI f( ˆR) GRAVITY.
Publication Type: Conference
Source(s): Acta Physica Polonica B, Proceedings Supplement. 2023, Vol. 16 Issue 6, p1-7. 7p.
Abstract: The planned next generation of detectors such as Einstein Telescope, Cosmic Explorer, and space-based detectors such as LISA are likely detect gravitational waves signals more frequently than the current generation LIGO detectors. With such an increase...
STRONG LENSING OF GRAVITATIONAL WAVES -- NEW OPPORTUNITIES FOR MULTIMESSENGER ASTRONOMY.
Publication Type: Conference
Source(s): Acta Physica Polonica B, Proceedings Supplement. 2023, Vol. 16 Issue 6, p1-8. 8p.
Abstract: We have entered the era of gravitational wave astronomy with routine detections of GW signals by the LIGO--Virgo--KAGRA interferometric detectors. Future perspectives are bright with the new generations of GW detectors: ground-based -- Einstein Telesco...
Random Convolutional Kernels for Space-Detector Based Gravitational Wave Signals.
Publication Type: Academic Journal
Source(s): Electronics (2079-9292). Oct2023, Vol. 12 Issue 20, p4360. 16p.
Abstract: Neural network models have entered the realm of gravitational wave detection, proving their effectiveness in identifying synthetic gravitational waves. However, these models rely on learned parameters, which necessitates time-consuming computations and...
Accretion/Ejection Phenomena and Emission-Line Profile (A)symmetries in Type-1 Active Galactic Nuclei.
Publication Type: Academic Journal
Source(s): Symmetry (20738994). Oct2023, Vol. 15 Issue 10, p1859. 15p.
Abstract: The distinct behaviors of blue- and redshifted broad emission-line shifts, emitted by ionic species with varying ionization potentials in active galactic nuclei (AGN), can be elucidated by considering the balance between radiation and gravitational for...
Parameter Inference for Coalescing Massive Black Hole Binaries Using Deep Learning.
Publication Type: Academic Journal
Source(s): Universe (2218-1997). Sep2023, Vol. 9 Issue 9, p407. 11p.
Abstract: In the 2030s, a new era of gravitational wave (GW) observations will dawn as multiple space-based GW detectors, such as the Laser Interferometer Space Antenna, Taiji, and TianQin, will open the millihertz window for GW astronomy. These detectors are po...
EXAMINING QUASINORMAL MODE INSTABILITY WITH THE PSEUDOSPECTRUM.
Publication Type: Conference
Source(s): Acta Physica Polonica B, Proceedings Supplement. 2023, Vol. 16 Issue 6, p1-8. 8p.
Abstract: The gravitational waves emitted by compact objects such as neutron stars or black holes are characterized by quasinormal modes (QNMs). The QNM frequencies encode information about the relic object, and -- in the most energetic cases -- are sensitive to...
GRAVITATIONAL WAVE ASTRONOMY -- AVANT LE DÉLUGE.
Publication Type: Conference
