XMM-Newton Observes the Intrabinary Shock of PSR J1959+2048

Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, Hongjun An, , | Summary: In a multi-orbit (100 ks) $mathrm{it XMM-Newton}$ exposure of the original black widow pulsar, PSR J1959+2048, we measure the strong orbital modulation caused by intrabinary shock (IBS) emission. The IBS light curve peak appears asymmetric, which […]

Warming up cold inflation

Kavli Affiliate: Peter W. Graham | First 5 Authors: William DeRocco, Peter W. Graham, Saarik Kalia, , | Summary: The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axions generically couple to gauge sectors. As the axion […]

A shock near the virial radius of the Perseus Cluster

Kavli Affiliate: Steven W. Allen | First 5 Authors: Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu, Xiaoyuan Zhang, Jelle S. Kaastra | Summary: Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperature profile near the virial radius (~r200) towards the […]

The Design and Integrated Performance of SPT-3G

Kavli Affiliate: C. L. Kuo | First 5 Authors: J. A. Sobrin, A. J. Anderson, A. N. Bender, B. A. Benson, D. Dutcher | Summary: SPT-3G is the third survey receiver operating on the South Pole Telescope dedicated to high-resolution observations of the cosmic microwave background (CMB). Sensitive measurements of the temperature and polarization anisotropies […]

The AGORA High-resolution Galaxy Simulations Comparison Project. III: Cosmological zoom-in simulation of a Milky Way-mass halo

Kavli Affiliate: Tom Abel | First 5 Authors: Santi Roca-Fàbrega, Ji-hoon Kim, Loic Hausammann, Kentaro Nagamine, Johnny W. Powell | Summary: We present a suite of high-resolution cosmological zoom-in simulations to $z=4$ of a $10^{12},{rm M}_{odot}$ halo at $z=0$, obtained using seven contemporary astrophysical simulation codes widely used in the numerical galaxy formation community. Physics […]
