Using gravitational-wave observations and quasi-universal relations to constrain the maximum mass of neutron stars
Combining the GW observations of merging systems of binary neutron stars and quasi-universal relations, we set constraints on the maximum mass that can be attained by nonrotating stellar models ofExpand
New Constraints on Radii and Tidal Deformabilities of Neutron Stars from GW170817.
We explore in a parameterized manner a very large range of physically plausible equations of state (EOSs) for compact stars for matter that is either purely hadronic or that exhibits a phaseExpand
A lower bound on the maximum mass if the secondary in GW190814 was once a rapidly spinning neutron star
The recent detection of GW190814 featured the merger of a binary with a primary having a mass of $\sim 23\,M_{\odot}$ and a secondary with a mass of $\sim 2.6\,M_{\odot}$. While the primary was mostExpand
Signatures of Quark-Hadron Phase Transitions in General-Relativistic Neutron-Star Mergers.
Merging binaries of neutron-stars are not only strong sources of gravitational waves, but also have the potential of revealing states of matter at densities and temperatures not accessible inExpand
Beyond second-order convergence in simulations of magnetized binary neutron stars with realistic microphysics
We investigate the impact of using high-order numerical methods to study the merger of magnetised neutron stars with finite-temperature microphysics and neutrino cooling in full general relativity.Expand
Electromagnetic precursors to gravitational wave events: Numerical simulations of flaring in pre-merger binary neutron star magnetospheres
The detection of gravitational waves from neutron star merger events has opened up a new field of multi-messenger astronomy linking gravitational waves events to short-gamma ray bursts and kilonovaExpand
On the stability and maximum mass of differentially rotating relativistic stars
The stability properties of rotating relativistic stars against prompt gravitational collapse to a black hole are rather well understood for uniformly rotating models. This is not the case forExpand
On the deconfinement phase transition in neutron-star mergers
We study in detail the nuclear aspects of a neutron-star merger in which deconfinement to quark matter takes place. For this purpose, we make use of the Chiral Mean Field (CMF) model, an effectiveExpand
Impact of high spins on the ejection of mass in GW170817
Following the detection of GW170817 and the accompanying kilonova AT2017gfo, it has become crucial to model and understand the various channels through which mass is ejected in neutron-star binaryExpand
Constrained transport and adaptive mesh refinement in the Black Hole Accretion Code
Worldwide very long baseline radio interferometry arrays are expected to obtain horizon-scale images of supermassive black hole candidates as well as of relativistic jets in several nearby activeExpand
