Broadband X-ray timing and spectral characteristics of the accretion-powered millisecond X-ray pulsar MAXI J1816$-$195

Kavli Affiliate: Renxin Xu | First 5 Authors: Zhaosheng Li, Lucien Kuiper, Mingyu Ge, Maurizio Falanga, Juri Poutanen | Summary: We studied the broadband X-ray timing and spectral behaviors of the newly confirmed accreting millisecond X-ray pulsar MAXI J1816$-$195 during its 2022 outburst. We used the data from Insight-HXMT ME/HE, NICER and NuSTAR which cover […]

Anatomy of plasmons in generic Luttinger semimetals

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Ipsita Mandal, , , | Summary: We investigate the parameter regimes favourable for the emergence of plasmons in isotropic, anisotropic, and band-mass symmetric and asymmetric Luttinger semimetals (LSMs). An LSM harbours a quadratic band-crossing point (QBCP) in its bandstructure, where the upper and lower branches […]

Improved bounds on the bosonic dark matter with pulsars in the Milky Way

Kavli Affiliate: Lijing Shao | First 5 Authors: Dicong Liang, Lijing Shao, , , | Summary: Neutron stars (NSs) can be used to constrain dark matter (DM) since a NS can transform into a black hole (BH) if it captures sufficient DM particles and exceeds the Chandrasekhar limit. We extend earlier work and for the […]

Active galactic nuclei feedback in an elliptical galaxy (III): the impacts and fate of cosmological inflow

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bocheng Zhu, Feng Yuan, Suoqing Ji, Yingjie Peng, Luis C. Ho | Summary: The cosmological inflow of a galaxy is speculated to be able to enter the galaxy and enhance the star formation rate (SFR) and black hole accretion rate (BHAR). In this paper, by performing high-resolution […]

DESI survey validation data in the COSMOS/HSC field: Cool gas trace main sequence star-forming galaxies at the cosmic noon

Kavli Affiliate: Linhua Jiang | First 5 Authors: Siwei Zou, Linhua Jiang, Zheng Cai, John Moustakas, Zechang Sun | Summary: We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument (DESI) survey validation data in the Cosmic Evolution Survey (COSMOS) and Hyper Suprime-Cam (HSC) field. We […]

Quantum $z=2$ Lifshitz criticality in one-dimensional interacting fermions

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We consider Lifshitz criticality (LC) with the dynamical critical exponent $z=2$ in one-dimensional interacting fermions with a filled Dirac Sea. We report that interactions have crucial effects on Lifshitz criticality. Single particle excitations are destabilized by interaction and decay into […]

Wet Compaction to a Blue Nugget: a Critical Phase in Galaxy Evolution

Sharon Lapiner, Avishai Dekel, Jonathan Freundlich, Omri Ginzburg, Fangzhou Jiang | Summary: [[{“value”:”We utilize high-resolution cosmological simulations to reveal that high-redshift galaxies tend to undergo a robust `wet compaction’ event when near a `golden’ stellar mass of $sim 10^{10} M_{odot}$. This is a gaseous shrinkage to a compact star-forming phase, a `blue nugget’ (BN), followed […]
