We are all enjoying the dawn of a new era with multiple direct detections of gravitational waves from merging black holes and eagerly a waiting a merger with at least one neutron star. Here, I will present my ongoing efforts and my view on prospects to identify and characterize an electromagnetic counterpart. Among the various models for electromagnetic emission from binary neutron...

Since the first direct detection of gravitational waves in 2015, a new window of discovery in Physics has opened up. However, in order to use gravitational waves as probes of cosmology and fundamental Physics, an electromagnetic counterpart must be detected. As the sky localisation for a gravitational wave detection is large, detected transient sources from follow-up and...

Magnetized compact objects are capable of generating strong intermittent outflows resembling coronal mass ejections from the sun. Internal shocks in these outflows can produce bright transients with a broad spectrum. This activity should be especially strong for differentially rotating objects formed in mergers. For instance, white dwarf mergers should produce bright transients, even...

413. What GW detections can tell us about jet structure of short GRBs

The peak magnitude for orphan afterglows from the jets of gravitational wave (GW) detected BH/NS-NS mergers highly depends on the jet half-opening angle. For a short GRB with a homogeneous jet structure, the jet half opening angle that gives an orphan afterglow viewed at the typical inclination for a GW detected event, 38 degrees, that is brighter at optical frequencies than...

414. Binary Black Hole Mergers from Field Triples: Properties, Rates, and the Impact of Stellar Evolution

Silvia Toonen

I'll be present our recent paper on black hole mergers that occur due to secular evolution in stellar triples. I'll show the expected rates and characteristics and what sets them apart from other formation channels.
