Two lensed star candidates at behind the galaxy cluster MACS J0647.7+7015
Ashish Kumar Meena, Adi Zitrin, Yolanda Jiménez-Teja +24
We report the discovery of two extremely magnified lensed star candidates behind the galaxy cluster MACS J0647.7+7015, in recent multi-band James Webb Space Telescope (JWST) NIRCam…
JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc
E. Vanzella, A. Claeyssens, B. Welch +27
Star cluster formation in the early universe and their contribution to reionization remains to date largely unconstrained. Here we present JWST/NIRCam imaging of the most highly ma…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
Compact dust emission in a gravitationally lensed massive quiescent galaxy at z = 2.15 revealed in ~130 pc-resolution observations by ALMA
Takahiro Morishita, Abdurro'uf, Hiroyuki Hirashita +3
We present new observations of MRG-M2129, a quiescent galaxy at z = 2.15 with the Atacama Large Millimeter/submillimeter Array (ALMA). With the combination of the gravitational len…
A Multiwavelength view of IC 860: What Is in Action inside Quenching Galaxies
Yuanze Luo, Kate Rowlands, Katherine Alatalo +15
We present a multiwavelength study of IC 860, a nearby post-starburst galaxy at the early stage of transitioning from blue and star-forming to red and quiescent. Optical images rev…
JWST Imaging of Earendel, the Extremely Magnified Star at Redshift
Brian Welch, Dan Coe, Erik Zackrisson +60
The gravitationally lensed star WHL0137-LS, nicknamed Earendel, was identified with a photometric redshift based on images taken with the Hubble Space Tele…
Dissecting Nearby Galaxies with piXedfit: II. Spatially Resolved Scaling Relations Among Stars, Dust, and Gas
Abdurro'uf, Yen-Ting Lin, Hiroyuki Hirashita +5
We study spatially resolved scaling relations among stars, dust, and gas in ten nearby spiral galaxies. In a preceding paper Abdurro'uf et al. (2022), we have derived spatially res…
