Spectrum Prediction With Deep 3D Pyramid Vision Transformer Learning

Autor: Pan, Guangliang, Wu, Qihui, Zhou, Bo, Li, Jie, Wang, Wei, Ding, Guoru, Yau, David K. Y.

In this paper, we propose a deep learning (DL)-based task-driven spectrum prediction framework, named DeepSPred. The DeepSPred comprises a feature encoder and a task predictor, where the encoder extracts spectrum usage pattern features, and the predi

HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ($G=9.0$ mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of $3.9 \pm 0.044$ $R_\oplus$ (HIP 9618 b) and $3.343 \pm 0.039$ $R_\oplus$ (HIP 9618 c)

XMM-Newton and NuSTAR observations of the compact millisecond pulsar binary PSR~J1653$-$0158

Autor: Long, Jane SiNan, kong, Albert K. H., Wu, Kinwah, Takata, Jumpei, Han, Qin, Hui, David C. Y., Li, Kwan Lok

We have presented the first joint {\it XMM-Newton} and {\it NuSTAR} analysis of the millisecond pulsar (MSP) binary PSR J1653$-$0158. The 75-minute orbital period inferred from optical and gamma-ray observations together with the 1.97-ms pulsation in

We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in TESS photometry. To characterise the system, we performed and retrieved CHEOPS, TESS, and ground-based
