Outside-In Evolution with a Twist: Metallicity Gradients and Asymmetries in the SMC
M. Navabi, R. Carrera, N. E. D. Noël +1
Taking advantage of the near-infrared calcium triplet lines, we determine metallicities for a sample of more than 3,500 red giant stars in the field of the Small Magellanic Cloud (…

A DECADE of dwarfs: first detection of weak lensing around spectroscopically confirmed low-mass galaxies
Chun-Hao To, Chihway Chang, Dhayaa Anbajagane +35
We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECA…

The DECam MAGIC Survey: A Wide-field Photometric Metallicity Study of the Sculptor Dwarf Spheroidal Galaxy
Fabrícia O. Barbosa, Anirudh Chiti, Guilherme Limberg +26
The metallicity distribution function and internal chemical variations of a galaxy are fundamental to understand its formation and assembly history. In this work, we analyze photom…
