Confidently Wrong: Why Ignoring Binaries Biases IMF Inference at Large Sample Sizes
Anna L. Rosen
The stellar initial mass function (IMF) high-mass slope is routinely measured by fitting single-star models to photometric samples that contain 20-90% unresolved binaries. Thi…
Investigating the Gamma-Ray Emission from Explosive Dispersal Outflows with Fermi-LAT
Paarmita Pandey, Stephen C. Lenker, Laura A. Lopez +6
We present the first systematic study of explosive dispersal outflows (EDOs) as potential sources of high-energy emission in the Milky Way. EDOs are energetic outflows produced dur…
Taming the Tarantula: How Stellar Wind Feedback Shapes Gas and Dust in 30 Doradus
Jennifer A. Rodriguez, Laura A. Lopez, Lachlan Lancaster +5
Observations of massive star-forming regions show that classical stellar wind models over-predict the luminosity of the X-ray emitting gas, indicating a significant fraction of win…
The High-resolution Accretion Disks of Embedded protoStars (HADES) simulations. I. Impact of Protostellar Magnetic Fields on the Accretion Modes
Brandt A. L. Gaches, Jonathan C. Tan, Anna L. Rosen +1
How embedded, actively accreting low-mass protostars accrete their mass is still greatly debated. Observations are now piecing together the puzzle of embedded protostellar accretio…
Detection of Diffuse Hot Gas Around the Young, Potential Superstar Cluster H72.97-69.39
Trinity L. Webb, Jennifer A. Rodriguez, Laura A. Lopez +6
We present the first Chandra X-ray observations of H72.97-69.39, a highly-embedded, potential super-star cluster (SSC) in its infancy located in the star-forming complex N79 of the…
Constraining the Diffusion Coefficient and Cosmic-Ray Acceleration Efficiency using Gamma-ray Emission from the Star-Forming Region RCW 38
Paarmita Pandey, Laura A. Lopez, Anna L. Rosen +3
Stellar winds from massive stars may be significant sources of cosmic rays (CRs). To investigate this connection, we report a detailed study of gamma-ray emission near the young Mi…
