Classifying the equation of state from rotating core collapse gravitational waves with deep learning

نویسندگان

چکیده

In this paper, we seek to answer the question "given a rotating core collapse gravitational wave signal, can determine its nuclear equation of state?". To question, employ deep convolutional neural networks learn visual and temporal patterns embedded within (GW) signals in order predict state (EOS). Using 1824 GW simulations by Richers et al. (2017), which has 18 different EOS, consider be classic multi-class image classification sequence problem. We attain up 72\% correct classifications test set, if "top 5" most probable labels, increases 97\%, demonstrating that there is moderate measurable dependence signal on EOS.

Gravitational Waves from Axisymmetric, Rotating Stellar Core Collapse

We have carried out an extensive set of two-dimensional, axisymmetric, purely-hydrodynamic calculations of rotational stellar core collapse with a realistic, finite-temperature nuclear equation of state and realistic massive star progenitor models. For each of the total number of 72 different simulations we performed, the gravitational wave signature was extracted via the quadrupole formula in ...

Gravitational Waves from Gravitational Collapse

Gravitational wave emission from stellar collapse has been studied for more than three decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular momentum profiles, properly treat microphysics issues, account for general relativity, and examine non-axisymmetric effects in three dimensions. Such simulations predict that g...

Gravitational waves from axisymmetric rotating stellar core collapse to a neutron star in full general relativity

Axisymmetric numerical simulations of rotating stellar core collapse to a neutron star are performed in the framework of full general relativity. The so-called Cartoon method, in which the Einstein field equations are solved in the Cartesian coordinates and the axisymmetric condition is imposed around the y = 0 plane, is adopted. The hydrodynamic equations are solved in the cylindrical coordina...

Core-collapse supernovae and gravitational waves

Core-collapse supernovae are dramatic events with a rich phenomenology, including gravitational radiation. Simulations of these events in multiple spatial dimensions with energyand angle-dependent neutrino transport are still in their infancy. Core collapse and bounce in a supernova in our galaxy may well be visible by firstgeneration LIGO, but detailed understanding waits on improvements in mo...
