Equilibrium models of star formation successfully derive the globally-averaged Kennicutt-Schmidt (KS) relation, positing that star formation rates (SFRs) are self- regulated by the turbulence in the interstellar medium (ISM) generated by stellar feedback. However, these models make assumptions that may not be achieved in realistic galaxy systems. Cosmological zoom-in simulations,...
Astronomy has entered a “multimessenger” era: one that combines electromagnetic “sight” with gravitational “touch.” This dissertation serves as a roadmap of the multimessenger frontier, to join the littered environments of dead and dying starswith their unclear origins. To uncover stars’ innermost secrets, we explore rare, transient glimpses into single, double,...
We establish the criterion for chaos in three-planet systems, for systems similar to those discovered by the Kepler spacecraft. Our main results are as follows: (i) The simplest criterion, which is based on overlapping mean motion resonances (MMRs), only agrees with numerical simulations at a very crude level. (ii) Much...

In this thesis, I explore the formation and evolution of neutron stars and millisecondpulsar populations in globular clusters using N-body simulations. In particular, I examine how the number of millisecond pulsars and the pulsar properties, including binary
properties and different pulsar types, depend on the dynamical cluster environment. I
demonstrate...
The field of time-domain astronomy has seen significant advancements in the latest years as increasingly sensitive, deep and wide-field surveys of the sky at all wavelengths are being carried out more and more frequently. Furthermore, the addition of gravitational wave detectors around the world has opened an entirely new window...
One of the most pressing open questions in star formation is the role of magnetic fields relative to turbulence and gravity, and how these three processes set the stellar initial mass function and star formation efficiency. In this work, we present the state of BLAST-TNG (the Balloon-borne Large Aperture Submillimeter...
Neutron star mergers instigate a wealth of observable astrophysical signals, offering key insights into interdisciplinary questions in stellar astronomy, nuclear physics, cosmology, and atomic physics. The coalescence of neutron stars and/or black holes produces gravitational wave emission, only recently accessible to ground-based laser-interferometric detectors. Additionally, these mergers can incite emission...
Astronomers are studying how young stellar objects (YSOs) develop and accrete mass. The variability of the YSO brightness can give information about the rate of accretion and the growth of these young stars. The YSOs described in this project are found in the Large Magellanic Cloud, a galaxy nearby to...
Due to the unprecedented sensitivity of the Advanced LIGO--Virgo network, in less than ~5 years the field of gravitational-wave astrophysics has evolved from speculating about the properties of compact binary mergers to having an observed population that facilitates astrophysical inference. These observations encode information about their progenitor stellar systems ---...
