A search for pulsars around Sgr A* in the first Event Horizon Telescope dataset

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Pablo Torne, Kuo Liu, Ralph P. Eatough, Jompoj Wongphechauxsorn, James M. Cordes | Summary: The Event Horizon Telescope (EHT) observed in 2017 the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz ($lambda$=1.3 mm). The […]

Extending the Chemical Reach of the H3 Survey: Detailed Abundances of the Dwarf-galaxy Stellar Stream Wukong/LMS-1

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Guilherme Limberg, Alexander P. Ji, Rohan P. Naidu, Anirudh Chiti, Silvia Rossi | Summary: We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < rm[Fe/H] lesssim -1.3$). We find abundance patterns that are effectively […]

r-process Abundance Patterns in the Globular Cluster M92

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Evan N. Kirby, Alexander P. Ji, Mikhail Kovalev, , | Summary: Whereas light element abundance variations are a hallmark of globular clusters, there is little evidence for variation in neutron-capture elements. A significant exception is M15, which shows a star-to-star dispersion in neutron-capture abundances of at […]

Identifying strongly lensed gravitational waves through their phase consistency

Kavli Affiliate: Wayne Hu | First 5 Authors: Jose María Ezquiaga, Wayne Hu, Rico K. L. Lo, , | Summary: Strongly lensed gravitational waves (GWs) from binary coalescence manifest as repeated chirps from the original merger. At the detectors, the phase of the lensed GWs and its arrival time differences will be consistent modulo a […]

Two of a Kind: Comparing big and small black holes in binaries with gravitational waves

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Maya Fishbach, Daniel E. Holz, , | Summary: When modeling the population of merging binary black holes, analyses have generally focused on characterizing the distribution of primary (i.e. more massive) black holes in the binary, while simplistic prescriptions are used for the distribution […]
