Nonthermal Electrons in Radiatively Inefficient Accretion Flow Models of Sagittarius A
We investigate radiatively inefficient accretion flow models for Sgr A*, the supermassive black hole in our Galactic center, in light of new observational constraints. Confirmation of linear…
Electromagnetic counterparts of compact object mergers powered by the radioactive decay of r‐process nuclei
The most promising astrophysical sources of kHz gravitational waves (GWs) are the inspiral and merger of binary neutron star(NS)/black hole systems. Maximizing the scientific return of a GW detection…
ON THE MAXIMUM LUMINOSITY OF GALAXIES AND THEIR CENTRAL BLACK HOLES: FEEDBACK FROM MOMENTUM-DRIVEN WINDS
We investigate large-scale galactic winds driven by momentum deposition. Momentum injection is provided by (1) radiation pressure produced by the continuum absorption and scattering of photons on…
Origin of the heavy elements in binary neutron-star mergers from a gravitational-wave event
TLDR
The ejected mass and a merger rate inferred from GW170817 imply that such mergers are a dominant mode of r-process production in the Universe.
Optical flares from the tidal disruption of stars by massive black holes
A star that wanders too close to a massive black hole (BH) is shredded by the BH’s tidal gravity. Stellar gas falls back to the BH at a rate initially exceeding the Eddington rate, releasing a flare…
A Possible Relativistic Jetted Outburst from a Massive Black Hole Fed by a Tidally Disrupted Star
TLDR
Observations suggest a sudden accretion event onto a central MBH of mass about 106 to 107 solar masses, which leads to a natural analogy of Sw 1644+57 to a temporary smaller-scale blazar.
Radiation Pressure-supported Starburst Disks and Active Galactic Nucleus Fueling
We consider the structure of marginally Toomre-stable starburst disks under the assumption that radiation pressure on dust grains provides the dominant vertical support against gravity. This…
Dynamical friction and galaxy merging time-scales
The time-scale for galaxies within merging dark matter haloes to merge with each other is an important ingredient in galaxy formation models. Accurate estimates of merging time-scales are required…
Gusty, gaseous flows of FIRE: Galactic winds in cosmological simulations with explicit stellar feedback
We present an analysis of the galaxy-scale gaseous outflows from the Feedback in Realistic Environments (FIRE) simulations. This suite of hydrodynamic cosmological zoom simulations resolves formation…
Galaxies on FIRE (Feedback In Realistic Environments): stellar feedback explains cosmologically inefficient star formation
We present a series of high-resolution cosmological simulations of galaxy formation to z = 0, spanning halo masses ∼10^8–10^(13) M⊙, and stellar masses ∼10^4–10^(11) M⊙. Our simulations include fully…
