Sudden polarization angle jumps of the repeating fast radio burst FRB 20201124A

J. R. Niu, W. Y. Wang, J. C. Jiang +41

We report the first detection of polarization angle (PA) orthogonal jumps, a phenomenon previously only observed from radio pulsars, from a fast radio burst (FRB) source FRB 202011…

Periodic Radio and X-ray Emission from an Accreting White Dwarf Binary

Kovi Rose, Joshua Pritchard, Tara Murphy +26

Long period radio transients (LPTs) are coherent bursts of polarised radio emission that repeat periodically on timescales of minutes to hours. Little is known about the physical o…

Decadal evolution of a repeating fast radio burst source

P. Wang, J. S. Zhang, Y. P. Yang +48

The origin of fast radio bursts (FRBs), the brightest cosmic radio explosions, is still unknown. Bearing critical clues to FRBs' origin, the long-term evolution of FRBs has yet to…

Ninety percent circular polarization detected in a repeating fast radio burst

J. C. Jiang, J. W. Xu, J. R. Niu +34

Fast radio bursts (FRBs) are extra-galactic sources with unknown physical mechanisms. They emit millisecond-duration radio pulses with isotropic equivalent energy of $10^{36}\sim10…

Minor mergers and their impact on the kinematics of old and young stellar populations in disk galaxies

Y. Qu, P. Di Matteo, M. D. Lehnert +2

By means of N-body simulations we investigate the impact of minor mergers on the angular momentum and dynamical properties of the merger remnant. Our simulations cover a range of i…

The formation of a thick disk through the heating of a thin disk: Agreement with orbital eccentricities of stars in the solar neighborhood

P. Di Matteo, M. D. Lehnert, Y. Qu +1

We study the distribution of orbital eccentricities of stars in thick disks generated by the heating of a pre-existing thin stellar disk through a minor merger (mass ratio 1:10), u…

Size evolution of normal and compact galaxies in the EAGLE simulation

M. Furlong, R. G. Bower, R. A. Crain +7

We present the evolution of galaxy sizes, from redshift 2 to 0, for actively star forming and passive galaxies in the cosmological hydrodynamical 1003 cMpc3 simulation of the EAGLE…
