Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Janusz J. Petkowski, Sara Seager, , | Summary: Life is a complex, dynamic chemical system that requires a dense fluid solvent in which to take place. A common assumption is that the most likely solvent for life is liquid water, and some researchers argue that […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Guang-Xuan Lan, Ye Li, Zhuo Li, , | Summary: We present a method to estimate the detection expectations of host galaxies of long gamma-ray bursts (LGRBs) in the {it grizJHKL} bands. It is found that given the same limiting magnitude $m_{grizJHKL,rm lim}$ in each band, the {it […]
Kavli Affiliate: John Silverman | First 5 Authors: Angelo George, Ivana Damjanov, Marcin Sawicki, Stéphane Arnouts, Guillaume Desprez | Summary: We analyze the size evolution of $16000$ star-forming galaxies (SFGs) and $5000$ quiescent galaxies (QGs) with mass $M_*>10^{9.5}M_odot$ at $0.1<z<0.9$ from the COSMOS field using deep CLAUDS+HSC imaging in two rest-frame wavelengths, $3000$r{A} (UV light) […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Ruifeng Shi, Yang Huang, Xinyi Li, Huawei Zhang, | Summary: Deriving atmospheric parameters of a large sample of stars is of vital importance to understand the formation and evolution of the Milky Way. Photometric surveys, especially those with near-ultraviolet filters, can offer accurate measurements of stellar parameters, […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Jack Schulte, Joseph E. Rodriguez, Allyson Bieryla, Samuel N. Quinn, Karen A. Collins | Summary: Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery, the mysteries surrounding their origins remain. Here, we present nine new hot Jupiters […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Shuqi Fu, Linhua Jiang, Yuanhang Ning, Weiyang Liu, Zhiwei Pan | Summary: We present a study of a sample of 45 spectroscopically confirmed, UV luminous galaxies at $zsim 6$. They were selected as bright Lyman-break galaxies (LBGs) using deep multi-band optical images in more than 2 deg$^2$ […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Han Lin, Xiaofeng Wang, Jujia Zhang, Danfeng Xiang, Tianmeng Zhang | Summary: We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanning the phases from about 1 to […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Rennan Barkana, Anastasia Fialkov, , | Summary: The efficiency of radio emission is an important unknown parameter of early galaxies at cosmic dawn, as models with high efficiency have been shown to modify the cosmological 21-cm signal substantially, deepening the absorption trough and boosting the […]
Kavli Affiliate: Sara Seager | First 5 Authors: Isabel Rebollido, Christopher C. Stark, Jens Kammerer, Marshall D. Perrin, Kellen Lawson | Summary: We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~$mu$m provide an unprecedentedly clear view of […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Huiling Chen, Yang Huang, Wei Zhu, Timothy C. Beers, Renjing Xie | Summary: A recent study by Hon et al. reported that a close-in planet around the red clump star, 8 UMi, should have been engulfed during the expansion phase of the stellar evolution. They explained the […]
