First direct carbon abundance measured at in the lensed galaxy MACS0647JD
Tiger Yu-Yang Hsiao, Michael W. Topping, Dan Coe +7
Investigating the metal enrichment in the early universe helps us constrain theories about the first stars and study the ages of galaxies. The lensed galaxy MACS0647JD at $z=10.…
JWST view of four infant galaxies at z=8.31-8.49 in the MACS0416 field and implications for reionization
Zhiyuan Ma, Bangzheng Sun, Cheng Cheng +34
New JWST/NIRCam wide-field slitless spectroscopy provides redshifts for four z>8 galaxies located behind the lensing cluster MACS J0416.1-2403. Two of them, "Y1" and "JD", have pre…
The significant contribution of supersoft X-ray Sources to the nebular HeII line emission
Dian P. Triani, Rosanne Di Stefano, Tiger Yu-yang Hsiao +1
Nebular spectral lines provide insight into the properties of the interstellar medium (ISM) and the ionizing radiation within galaxies. The presence of high-energy ionization lines…
JWST NIRSpec High-resolution Spectroscopy of MACS0647-JD at z=10.167: Resolved [OII] Doublet and Electron Density in an Early Galaxy
Abdurro'uf, Rebecca L. Larson, Dan Coe +26
We present JWST/NIRSpec high-resolution spectroscopy G395H/F290LP of MACS0647-JD, a gravitationally lensed galaxy merger at . The new spectroscopy, which is acquired for…
JWST MIRI detections of H and [O III] and direct metallicity measurement of the lensed galaxy MACS0647JD
Tiger Yu-Yang Hsiao, Javier Álvarez-Márquez, Dan Coe +30
JWST spectroscopy has revolutionized our understanding of galaxies in the early universe. Covering wavelengths up to , NIRSpec can detect rest-frame optical emission…
Unveiling the Cosmic Gems Arc at with JWST NIRCam
Larry D. Bradley, Angela Adamo, Eros Vanzella +22
We present recent JWST NIRCam imaging observations of SPT0615-JD (also known as the Cosmic Gems Arc), lensed by the galaxy cluster SPT-CL J0615-5746. The 5 arcsec long arc is the m…
Identification of 40 gravitationally magnified stars in a galaxy at redshift of 0.725
Yoshinobu Fudamoto, Fengwu Sun, Jose M. Diego +44
Strong gravitational magnifications enable to detect faint background sources, resolve their internal structures, and even identify individual stars in distant galaxies. Highly mag…
Polycyclic aromatic hydrocarbon (PAH) luminous galaxies in JWST CEERS data
Yu-Wei Lin, Cossas K. -W. Wu, Chih-Teng Ling +9
It has been an unanswered question how many dusty galaxies have been undetected from the state-of-the-art observational surveys. JWST enables us to detect faint IR galaxies that ha…
Bound star clusters observed in a lensed galaxy 460 Myr after the Big Bang
Angela Adamo, Larry D. Bradley, Eros Vanzella +25
The Cosmic Gems arc is among the brightest and highly magnified galaxies observed at redshift . However, it is an intrinsically UV faint galaxy, in the range of those no…
