Black Hole Survival Guide: Searching for Stars in the Galactic Center That Endure Partial Tidal Disruption
Rewa Clark Bush, Samantha C. Wu, Rosa Wallace Everson +3
Once per 10,000-100,000 years, an unlucky star may experience a close encounter with a supermassive black hole (SMBH), partially or fully tearing apart the star in an exceedingly b…
The Evolution of Binaries Embedded Within Common Envelopes
Alejandra Rosselli-Calderon, Ricardo Yarza, Ariadna Murguia-Berthier +5
Triple stellar systems allow us to study stellar processes that cannot be attained in binary stars. The evolutionary phases in which the stellar members undergo mass exchanges can…

From Feast to Famine: A Systematic Study of Accretion onto Oblique Pulsars with 3D GRMHD Simulations
Ariadna Murguia-Berthier, Kyle Parfrey, Alexander Tchekhovskoy +1
Disk-fed accretion onto neutron stars can power a wide range of astrophysical sources ranging from X-ray binaries, to accretion powered millisecond pulsars, ultra-luminous X-ray so…
Bound Debris Expulsion from Neutron Star Merger Remnants
Yossef Zenati, Julian H. Krolik, Leonardo R. Werneck +4
Many studies have found that neutron star mergers leave a fraction of the stars' mass in bound orbits surrounding the resulting massive neutron star or black hole. This mass is a s…

Leonardo R. Werneck, Zachariah B. Etienne, Ariadna Murguia-Berthier +11
We have added support for realistic, microphysical, finite-temperature equations of state (EOS) and neutrino physics via a leakage scheme to IllinoisGRMHD, an open-source GRMHD cod…
On the jet-ejecta interaction in 3D GRMHD simulations of binary neutron star merger aftermath
Ore Gottlieb, Serena Moseley, Teresita Ramirez-Aguilar +3
Short -ray burst (sGRB) jets form in the aftermath of a neutron star merger, drill through disk winds and dynamical ejecta, and extend over four to five orders of magnitude in d…
Hydrodynamics and survivability during post-main-sequence planetary engulfment
Ricardo Yarza, Naela Razo Lopez, Ariadna Murguia-Berthier +6
The engulfment of substellar bodies (SBs, such as brown dwarfs and planets) by giant stars is a possible explanation for rapidly rotating giants, lithium-rich giants, and the prese…
Jet Formation in 3D GRMHD Simulations of Bondi-Hoyle-Lyttleton Accretion
Nicholas Kaaz, Ariadna Murguia-Berthier, Koushik Chatterjee +2
A black hole (BH) travelling through a uniform, gaseous medium is described by Bondi-Hoyle-Lyttleton (BHL) accretion. If the medium is magnetized, then the black hole can produce r…
Handing off the outcome of binary neutron star mergers for accurate and long-term post-merger simulations
Federico G. Lopez Armengol, Zachariah B. Etienne, Scott C. Noble +20
We perform binary neutron star (BNS) merger simulations in full dynamical general relativity with IllinoisGRMHD, on a Cartesian grid with adaptive-mesh refinement. After the remnan…

The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component p…
What determines the structure of short gamma-ray burst jets?
Gerardo Urrutia, Fabio De Colle, Ariadna Murguia-Berthier +1
The discovery of GRB 170817A, the first unambiguous off-axis short gamma-ray burst arising from a neutron star merger, has challenged our understanding of the angular structure of…
The Fate of the Merger Remnant in GW170817 and its Imprint on the Jet Structure
Ariadna Murguia-Berthier, Enrico Ramirez-Ruiz, Fabio De Colle +3
The first neutron star binary merger detected in gravitational waves, GW170817 and the subsequent detection of its emission across the electromagnetic spectrum showed that these sy…
On the maximum stellar rotation to form a black hole without an accompanying luminous transient
Ariadna Murguia-Berthier, Aldo Batta, Agnieszka Janiuk +4
The collapse of a massive star with low angular momentum content is commonly argued to result in the formation of a black hole without an accompanying bright transient. Our goal in…
Multi-Messenger Astronomy with Extremely Large Telescopes
