Constraining Delay Time Distribution of Binary Neutron Star Mergers from Host Galaxy Properties

2 code implementations29 Jul 2020 Kevin Spencer McCarthy, Zheng Zheng, Enrico Ramirez-Ruiz

Using a catalogue of local galaxies with inferred star formation histories and adopting a BNSM delay time distribution (DTD) model, we investigate the dependence of BNSM rate on an array of galaxy properties.

Common Envelope Wind Tunnel: The Effects of Binary Mass Ratio and Implications for the Accretion-Driven Growth of LIGO Binary Black Holes

1 code implementation29 Oct 2019 Soumi De, Morgan MacLeod, Rosa Wallace Everson, Andrea Antoni, Ilya Mandel, Enrico Ramirez-Ruiz

We demonstrate that the mass and spin accrued by these black holes per unit orbital tightening are directly related to the ratio of accretion to drag coefficients.

First results from the IllustrisTNG simulations: A tale of two elements -- chemical evolution of magnesium and europium

no code implementations11 Jul 2017 Jill P. Naiman, Annalisa Pillepich, Volker Springel, Enrico Ramirez-Ruiz, Paul Torrey, Mark Vogelsberger, Rüdiger Pakmor, Dylan Nelson, Federico Marinacci, Lars Hernquist, Rainer Weinberger, Shy Genel

To this end we use the magnesium to iron ratio as a proxy for the effects of our SNII and SNIa metal return prescription, and a means to compare our simulated abundances to a wide variety of galactic observations.
