Self-calibrating optical galaxy cluster selection bias using cluster, galaxy, and shear cross-correlations

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (3)

The clustering signals of galaxy clusters are powerful tools for self-calibrating the mass-observable relation and are complementary to cluster abunda......

Pulsar glitch in a strangeon star model - III. The recovery

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (3)

Strangeon star model has passed various observational tests, such as the massive pulsars and the tidal deformability during binary mergers. Pulsar gli......

Nitrogen enhancements 440 Myr after the big bang: supersolar N/O, a tidal disruption event, or a dense stellar cluster in GN-z11?

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (3)

Recent observations of GN-z11 with JWST/NIRSpec revealed numerous oxygen, carbon, nitrogen, and helium emission lines at z = 10.6. Using the measured ......

Cosmic evolution of radio-AGN feedback: confronting models with data

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (4)

Radio-mode feedback is a key ingredient in galaxy formation and evolution models, required to reproduce the observed properties of massive galaxies in......

Single-pulse analysis and average emission characteristics of PSR J1820-0427 from observations made with the MWA and uGMRT

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (4)

We have studied the pulse-to-pulse variability in PSR J1820-0427 and its frequency dependence using high-quality, wide-band observations made with the......

The role of baryons in self-interacting dark matter mergers

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (4)

Mergers of galaxy clusters are promising probes of dark matter (DM) physics. For example, an offset between the DM component and the galaxy distributi......

The cosmic web in Lyman-alpha emission

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (4)

We develop a comprehensive theoretical model for Lyman-alpha (Ly & alpha;) emission, from the scale of individual Ly & alpha; emitters (LAEs) ......

QPE or QPO? - Quasiperiodic activity in low-mass galaxy nuclei

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 523 (1)

Quasiperiodic eruptions (QPEs) from low-mass galaxy centres may result from accretion from a white dwarf in a very eccentric orbit about the central m......

Constraining the LyC escape fraction from LEGUS star clusters with SIGNALS H II region observations: a pilot study of NGC 628

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 524 (1)

The ionizing radiation of young and massive stars is a crucial form of stellar feedback. Most ionizing (Lyman-continuum; LyC, lambda< 912A) photons......

Atmospheres as windows into sub-Neptune interiors: coupled chemistry and structure of hydrogen-silane-water envelopes

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 524 (1)

Sub-Neptune exoplanets are commonly hypothesized to consist of a silicate-rich magma ocean topped by a hydrogen-rich atmosphere. Previous work studyin......

The oblateness of the Milky Way dark matter halo from the stellar streams of NGC 3201, M68, and Palomar 5

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 524 (2)

We explore constraints on the Milky Way dark matter halo oblateness using three stellar streams from globular clusters NGC3201, M68, and Palomar 5. Pr......

Lunar collision rate with primordial black holes

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 524 (2)

A recent letter studied cratering during collisions between rocky bodies and primordial black holes. Hydrodynamic simulations in that work showed that......

Time delay induced by plasma in strong lens systems

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 524 (2)

If the gravitational lens is surrounded by non-homogeneous plasma, in addition to the vacuum gravitational deflection, chromatic refraction occurs. Al......

Discovery of a radio jet in the Cloverleaf quasar at z=2.56

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 524 (3)

The fast growth of supermassive black holes and their feedback to the host galaxies play an important role in regulating the evolution of galaxies, es......

Trajectory-based RFI subtraction and calibration for radio interferometry

期刊: MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2023; 524 (3)

Radio interferometry calibration and radio frequency interference (RFI) removal are usually done separately. Here we show that jointly modelling the a......
