3D Binary Neutron Star Merger Ejecta Evolution up to Seconds Timescale: Dynamics, Element Distribution, and Light Curves
Luis Felipe Longo Micchi, Fabio Magistrelli, Maximilian Jacobi +1
We present long-term, three-dimensional simulations of ejecta from four binary neutron star mergers to second-long time-scales. Numerical-relativity data serve as boundary conditio…
Magnetar Formation from Accretion Induced Collapse of White Dwarfs
Luís Felipe Longo Micchi, Patrick Chi-Kit Cheong, David Radice
We aim to characterize the post-collapse evolution of accretion-induced collapse (AIC) remnants of rapidly rotating, magnetized white dwarfs, focusing on their rotational, magnetic…
Neutrino trapping and out-of-equilibrium effects in binary neutron star merger remnants
Pedro Luis Espino, Peter Hammond, David Radice +5
We study out-of-thermodynamic equilibrium effects in neutron star mergers with 3D general-relativistic neutrino-radiation large-eddy simulations. During merger, the cores of the ne…
Multimessenger Emission from the Accretion Induced Collapse of White Dwarfs
Luís Felipe Longo Micchi, David Radice, Cecilia Chirenti
We present fully general-relativistic three-dimensional numerical simulations of accretion-induced collapse (AIC) of white dwarfs (WDs). We evolve three different WD models (nonrot…
Spectrogram correlated stacking: A novel time-frequency domain analysis of the Stochastic Gravitational Wave Background
Ramit Dey, Luís Felipe Longo Micchi, Suvodip Mukherjee +1
The astrophysical stochastic gravitational wave background (SGWB) originates from numerous faint sub-threshold gravitational wave (GW) signals arising from the coalescing binary co…
Spicing up the recipe for echoes from exotic compact objects: orbital differences and corrections in rotating backgrounds
Luis Felipe Longo Micchi, Cecilia Chirenti
Recently it has been argued that near-horizon modifications of the standard (classical) black hole spacetime could lead to observable alterations of the gravitational waveform gene…
Spectroscopy of Extremal (and Near-Extremal) Kerr Black Holes
Marc Casals, Luís F. Longo Micchi
We investigate linear, spin-field perturbations of Kerr black holes in the extremal limit throughout the complex-frequency domain. We calculate quasi-normal modes of extremal Kerr,…
Bipolar ionization cones in the Extended Narrow-Line Region of nearby QSO2s
Thaisa Storchi-Bergmann, Bruno Dall'Agnol de Oliveira, Luis Felipe Longo Micchi +8
We have used narrow-band [OIII]4959,5007 and H+[NII] Hubble Space Telescope (HST) images of 9 luminous (L[OIII]erg s) type 2 QSOs with reds…
