Enrichment by Extragalactic First Stars in the Large Magellanic Cloud

Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Mohammad Mardini, Guilherme Limberg, Anna Frebel, Alexander P. Ji | Summary: The Large Magellanic Cloud (LMC) is the Milky Way’s most massive satellite galaxy, which only recently (~2 billion years ago) fell into our Galaxy. Since stellar atmospheres preserve their natal cloud’s composition, the LMC’s […]

Chronicling the reionization history at $6lesssim z lesssim 7$ with emergent quasar damping wings

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Dominika Ďurovčíková, Anna-Christina Eilers, Huanqing Chen, Sindhu Satyavolu, Girish Kulkarni | Summary: The spectra of high-redshift ($zgtrsim 6$) quasars contain valuable information on the progression of the Epoch of Reionization (EoR). At redshifts $z<6$, the observed Lyman-series forest shows that the intergalactic medium (IGM) is nearly […]

Highly-coherent quasi-periodic oscillations in the ‘heartbeat’ black hole X-ray binary IGR J17091-3624

Kavli Affiliate: Erin Kara | First 5 Authors: Jingyi Wang, Erin Kara, Jeroen Homan, James F. Steiner, Diego Altamirano | Summary: IGR J17091-3624 is a black hole X-ray binary (BHXB), often referred to as the ‘twin’ of GRS 1915+105 because it is the only other known BHXB that can show exotic ‘heartbeat’-like variability that is […]

The 2022 Outburst of IGR J17091-3624: Connecting the exotic GRS 1915+105 to standard black hole X-ray binaries

Kavli Affiliate: Erin Kara | First 5 Authors: Jingyi Wang, Erin Kara, Javier A. García, Diego Altamirano, Tomaso Belloni | Summary: While the standard X-ray variability of black hole X-ray binaries (BHXBs) is stochastic and noisy, there are two known BHXBs that exhibit exotic `heartbeat’-like variability in their light curves: GRS 1915+105 and IGR J17091-3624. […]

A long-period transiting substellar companion in the super-Jupiters to brown dwarfs mass regime and a prototypical warm-Jupiter detected by TESS

Kavli Affiliate: Avi Shporer | First 5 Authors: Matias I. Jones, Yared Reinarz, Rafael Brahm, Marcelo Tala Pinto, Jan Eberhardt | Summary: We report on the confirmation and follow-up characterization of two long-period transiting substellar companions on low-eccentricity orbits around TIC 4672985 and TOI-2529, whose transit events were detected by the TESS space mission. Ground-based […]

Parameterizing black hole orbits for adiabatic inspiral

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Scott A. Hughes, , , , | Summary: Adiabatic binary inspiral in the small mass ratio limit treats the small body as moving along a geodesic of a large Kerr black hole, with the geodesic slowly evolving due to radiative backreaction. Up to initial conditions, geodesics […]
