Merian: A Wide-Field Imaging Survey of Dwarf Galaxies at z~0.06-0.10
Shany Danieli, Erin Kado-Fong, Song Huang +32
We present the Merian Survey, an optical imaging survey optimized for studying the physical properties of bright star-forming dwarf galaxies. Merian is carried out with two medium-…
Exploring the interaction between the MW and LMC with a large sample of blue horizontal branch stars from the DESI survey
Amanda Byström, Sergey E. Koposov, Sophia Lilleengen +42
The Large Magellanic Cloud (LMC) is a Milky Way (MW) satellite that is massive enough to gravitationally attract the MW disc and inner halo, causing significant motion of the inner…
GD-1 Stellar Stream and Cocoon in the DESI Early Data Release
Monica Valluri, Parker Fagrelius, Sergey. E. Koposov +49
We present 115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence…
Extended Shock Breakout and Early Circumstellar Interaction in SN 2024ggi
Manisha Shrestha, K. Azalee Bostroem, David J. Sand +40
We present high-cadence photometric and spectroscopic observations of supernova (SN) 2024ggi, a Type II SN with flash spectroscopy features which exploded in the nearby galaxy NGC…
Early emission lines in SN 2024ggi revealed by high-resolution spectroscopy
Thallis Pessi, Régis Cartier, Emilio Hueichapan +6
We present an analysis of very early high-resolution spectroscopic observations of the Type II supernova (SN) 2024ggi, a nearby SN that occurred in the galaxy NGC 3621 at a distanc…
Taking the pulse of the outer Milky Way with HOWVAST: an RR Lyrae density profile out to 200 kpc
Gustavo E. Medina, Ricardo R. Muñoz, Jeffrey L. Carlin +4
In order to constrain the evolutionary history of the Milky Way, we hunt for faint RR Lyrae stars (RRLs) using Dark Energy Camera data from the High cadence Transient Survey (HiTS)…
The Power of High Precision Broadband Photometry: Tracing the Milky Way Density Profile with Blue Horizontal Branch stars in the Dark Energy Survey
Fengqing Yu, Ting S. Li, Joshua S. Speagle +9
Blue Horizontal Branch (BHB) stars, excellent distant tracers for probing the Milky Way's halo density profile, are distinguished in the vs color space from ano…
