Is the Nuclear Star Cluster a Bulge Fossil Fragment?
R. Michael Rich, Brian Thorsbro, Christian Johnson
The Milky Way nuclear star cluster (NSC) is unlike a conventional globular cluster: it contains a broad metallicity distribution and stellar populations formed over an extended int…
AT2024lhc and AT2024kmq in the landscape of featureless tidal disruption events
Yuhan Yao, Ryan Chornock, Andrew Mummery +39
We study AT2024kmq and AT2024lhc, two tidal disruption events (TDEs) with blue featureless spectra associated with high-mass black holes (). Both even…
A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
Supergiant GCIRS 22 in the Milky Way Nuclear Star Cluster: Revised alpha abundances
B. Thorsbro, S. Khalidy, R. M. Rich +7
Context: The chemical abundances of alpha-elements in Galactic Centre (GC) supergiants provide key insights into the chemical enrichment and star formation history of the Milky Way…
The First Chemical Census the Milky Way's Nuclear Star Cluster
Govind Nandakumar, Nils Ryde, Mathias Schultheis +4
An important step in understanding the formation and evolution of the Nuclear Star Cluster (NSC) is to investigate its chemistry and chemical evolution. Additionally, exploring the…
Chemical Abundances in the Nuclear Star Cluster of the Milky Way: alpha-Element Trends and Their Similarities with the Inner Bulge
N. Ryde, G. Nandakumar, M. Schultheis +15
A chemical characterization of the Galactic Center is essential for understanding its formation and structural evolution. Trends of alpha-elements, such as Mg, Si, and Ca, serve as…
Multi-iron subpopulations in Liller 1 from high resolution H-band spectroscopy
C. Fanelli, L. Origlia, R. M. Rich +7
We present a high resolution chemical study of a representative sample of 21 luminous giant stars of Liller~1, a complex stellar system in the Galactic bulge, based on H band spect…
Elemental Abundances in And XIX From Coadded Spectra
L. R. Cullinane, Karoline M. Gilbert, Ivanna Escala +6
With a luminosity similar to that of Milky Way dwarf spheroidal (dSph) systems like Sextans, but a spatial extent similar to that of ultradiffuse galaxies (UDGs), Andromeda (And) X…
X-shooter spectroscopy of Liller1 giant stars
D. A. Alvarez Garay, C. Fanelli, L. Origlia +8
We present the first comprehensive chemical study of a representative sample of 27 luminous red giant branch (RGB) stars belonging to Liller 1, a complex stellar system in the Gala…
Final Moments II: Observational Properties and Physical Modeling of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early-time ( days) spectra show transient, narrow emission lines…
Composition of Giants 1 North of the Galactic Center: Detailed Abundance Trends for 21 Elements Observed with IGRINS
Govind Nandakumar, Nils Ryde, Gregory Mace +10
We report the first high resolution, detailed abundances of 21 elements for giants in the Galactic bulge/bar within of the Galactic plane, where high extinction has rende…
