Kavli Affiliate: Robert A. Simcoe | First 5 Authors: , , , , | 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 ionized, while at $z>7$ the observed […]
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 […]
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.

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 […]

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 […]

Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Janusz J. Petkowski, Sara Seager, , | Summary: Life is a complex, dynamic chemical system that requires a dense fluid solvent in which to take place. A common assumption is that the most likely solvent for life is liquid water, and some researchers argue that […]
