Recent observations of binary black hole and binary neutron star mergers have ignited interest in the formation and evolution of compact-object binary systems. However, by the time a compact-object binary merges and produces gravitational-wave...

Neutron star merger GW 170817 was accompanied by a gamma-ray burst with luminosity L∼1047 erg/s, coming with a ~2 s delay after the gravitational waves. Observations also indicate the presence of a dark, ultra-relativistic envelope ejected promptly...

We have undertaken a novel census of red sources identified by their rest-frame far infrared colors using Planck and Herschel telescopes, and not by the Sunyaev-Z'eldovich effect (SZE). The vast majority of sources are high-redshift galaxy...

I will discuss recent work that lays out two methods to obtain direct measurements of the Galactic acceleration. First, I will review our recent work in using high precision spectrographs to measure the Galactic acceleration. These measurements can...

Turbulence is ubiquitous in astrophysical media and plays an essential role in a variety of fundamental astrophysical processes. The turbulent power-law spectra have been observed in the solar wind, the interstellar medium, the intracluster medium...

The observation of compact binary mergers by the LIGO/Virgo collaboration marked the dawn of a new era in astronomy. LISA will expand this vision by opening a new observational window at low frequencies. The gravitational radiation emitted by...
