CAPOS: The bulge Cluster APOgee Survey VIII. Final ASPCAP results for all clusters
Doug Geisler, Cesar Muñoz, Sandro Villanova +12
Bulge globular clusters(BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational difficultie…
The Galactic Bulge exploration VI.: Gaia Enceladus/Sausage RR Lyrae stars in the inner-central stellar halo of the Milky Way
Andrea Kunder, Zdenek Prudil, Antonela Monachesi +6
We present a view of the stellar halo in the inner-central regions of the Milky Way (R <~ 10 kpc) mapped by RR Lyrae stars. The combined BRAVA-RR/APOGEE RR Lyrae catalog is used to…
The Galactic Bulge exploration IV.: RR~Lyrae stars as traces of the Galactic bar -- 3D and 5D analysis, extinction variation
Z. Prudil, A. Kunder, L. Beraldo e Silva +10
We created new reddening maps and derived new extinction laws from visual to near-infrared passbands using improved RR~Lyrae period-absolute magnitude-metallicity relations, thus e…
On the impossibility of certain configurations
Jackson Philbrook, Benjamin Peet
This paper investigates the impossibility of certain configurations. Firstly, for , the result of \cite{gropp1992non} that is even and $n…
RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99
Evan Butler, Andrea Kunder, Zdenek Prudil +16
Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination.…
Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)
Roberta Paladini, Catherine Zucker, Robert Benjamin +67
A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…
Variations on Ramsey numbers and minimum numbers of monochromatic triangles in line -colorings of configurations
Jamie Bishop, Rebekah Kuss, Benjamin Peet
This paper begins by exploring some old and new results about Ramsey numbers and minimum numbers of monochromatic triangles in -colorings of complete graphs, both in the disjoin…
Blanco DECam Bulge Survey (BDBS) IV: Metallicity Distributions and Bulge Structure from 2.6 Million Red Clump Stars
Christian I. Johnson, R. Michael Rich, Iulia T. Simion +12
We present photometric metallicity measurements for a sample of 2.6 million bulge red clump stars extracted from the Blanco DECam Bulge Survey (BDBS). Similar to previous studies,…
Blanco DECam Bulge Survey (BDBS) V. Cleaning the foreground populations from Galactic bulge colour-magnitude diagrams using Gaia EDR3
Tommaso Marchetti, Christian I. Johnson, Meridith Joyce +8
The Blanco DECam Bulge Survey (BDBS) has imaged more than 200 square degrees of the southern Galactic bulge, providing photometry in the ugrizy filters for million uniqu…
Configurations of higher orders
Benjamin Peet
This paper begins by extending the notion of a combinatorial configuration of points and lines to a combinatorial configuration of points and planes that we refer to as configurati…
Spectroscopic Observations of Obscured Populations in the Inner Galaxy: 2MASS-GC02, Terzan 4, and the 200 km/s stellar peak
Andrea Kunder, Riley E. Crabb, Victor P. Debattista +2
The interpretation of potentially new and already known stellar structures located at low-latitudes is hindered by the presence of dense gas and dust, as observations toward these…
The Abundancy Index and Feebly Amicable Numbers
Jamie Bishop, Abigail Bozarth, Rebekah Kuss +1
This research explores the sum of divisors - - and the abundancy index given by the function . We give a generalization of amicable pairs - feebly amicable p…
Blanco DECam Bulge Survey (BDBS) III: A new view of the double red clump in the Milky Way bulge through luminosity and color distribution
Dongwook Lim, Andreas J. Koch-Hansen, Chul Chung +9
Red clump (RC) stars are one of the best stellar tracers of the structure of the Milky Way (MW) bulge. Here we report a new view of the double RC through luminosity and color distr…
Spectroscopic analysis of the bulge Globular Cluster ESO~456-SC38
Andrea Kunder, Evan Butler
It has been suggested that the oldest stellar populations in the Milky Way Galaxy are tightly bound and confined to the central regions of the Galaxy. This is one of the reasons wh…
The Blanco DECam Bulge Survey. I. The Survey Description and Early Results
R. Michael Rich, Christian I. Johnson, Michael Young +18
The Blanco Dark Energy Camera (DECam) Bulge survey is a Vera Rubin Observatory (LSST) pathfinder imaging survey, spanning sq. deg. of the Southern Galactic bulge, $-2^\c…
Blanco DECam Bulge Survey (BDBS) II: Project Performance, Data Analysis, and Early Science Results
Christian I. Johnson, R. Michael Rich, Michael D. Young +7
The Blanco DECam Bulge Survey (BDBS) imaged more than 200 square degrees of the Southern Galactic bulge using the ugrizY filters of the Dark Energy Camera, and produced point sprea…
The Magellanic Edges Survey I. Description and First Results
L. R. Cullinane, A. D. Mackey, G. S. Da Costa +6
We present an overview of, and first science results from, the Magellanic Edges Survey (MagES), an ongoing spectroscopic survey mapping the kinematics of red clump and red giant br…
