  1. 587. Current status of DECIGO and B-DECIGO
    Kentaro Komori
    12/07/2024, 09:00
    Plenary talk

    DECIGO (DECi-Hertz Gravitational-wave Observatory) and B-DECIGO are interferometric satellites expected to be launched in Japan around the 2030s targeting the observation of gravitational waves (GWs) from 0.1 Hz to 10 Hz. These missions will unveil populations of intermediate-mass black hole mergers, provide frequent opportunities to localize the host galaxy of a binary neutron star before its...

  2. 612. Inertial sensor for TianQin project
    Ze-Bing Zhou
    12/07/2024, 09:30
    Plenary talk

    TianQin is a Chinese space-borne gravitational wave detector proposed in 2014, and aims to detect gravitational waves in the frequency range of 1mHz ~ 1 Hz, with three earth orbiting satellites with an orbital radius of about 105 km forming an equilateral triangle with side length 1.7×105 km. The free falling test masses are used as inertial references to provide measurement points for...

  3. 599. AI in the Cosmos: Application of neural networks for modeling multiwavelength and multimessenger data from blazar observations
    Narek Sahakyan (ICRANet-Armenia)
    12/07/2024, 10:00
    Plenary talk

    The integration of Artificial Intelligence (AI) into astronomy and astrophysics marks a transformative era in the exploration of the Universe, enhancing the analysis of vast data sets with unparalleled efficiency and precision. AI is revolutionizing the usability of observational data, expanding our understanding of various cosmic phenomena. Blazar research particularly benefits from the...

  4. 574. On the Quantum Nature of the Coulombic Interaction
    Abhay Ashtekar (Institute fro Gravitation & the Cosmos, Penn State)
    12/07/2024, 10:30
    Plenary talk

    The interface between Quantum Information and Quantum Field Theory --especially Quantum Gravity -- is emerging as a forefront area of fundamental physics. But there is some tension between the way the basic concepts are commonly understood by the two communities. In particular, are the `Coulombic modes' of the gravitational field sourced by quantum matter quantum mechanical? They are not...

  5. 605. Searching for Nanohertz Gravitational Waves with Pulsar Timing Arrays
    Sarah Vigeland
    12/07/2024, 11:30
    Plenary talk

    Pulsar timing arrays are sensitive to low-frequency gravitational waves with periods of months to decades. They do so by precisely timing a collection of millisecond pulsars, whose extremely stable rotation makes them ideal for measuring perturbations in spacetime. Gravitational waves induce correlations in the pulse arrival times that follows a characteristic pattern known as the...

  6. 576. KAGRA, LIGO, VIRGO observations
    Marta Colleoni
    12/07/2024, 12:00
    Plenary talk

    After the first groundbreaking observation of gravitational waves emitted by the collision of two black holes on 14 September 2015, the LIGO-Virgo-KAGRA network has completed three successful observing runs yielding nearly a hundred events. All detections were compatible with short transients emitted by the coalescence of compact binaries composed of black holes and/or neutron stars. The first...

  7. 598. The Einstein Telescope project: a third generation of Gravitational Wave detector on the Earth.
    Fulvio Ricci (Universita' di Roma La Sapienza, I-00185 Roma, Italy)
    12/07/2024, 12:30
    Plenary talk

    In the field of gravitational wave (GW) detection, groundbreaking discoveries like those made by the LIGO, Virgo, and KAGRA collaborations signify the culmination of extensive interdisciplinary efforts spanning various research fields. These detectors grapple with numerous noise sources that undermine their sensitivity. To surmount these challenges, we are exploring strategies that harness...

    Plenary talk
  9. 604. Unleashing the scientific potential of LISA
    Daniele Vetrugno
    Plenary talk

    LISA is considered by a growing part of the relevant scientific community to be one of the most exciting and impacting observatories from space in the next 30 years. The scientific case it carries with it is enormous, ranging from the supermassive black holes to the Galactic binaries’ astrophysics via cosmology and fundamental physics. Not to mention its invaluable discovery potential. Added...
