The Origin of the Fermi Halo-like Emission: A New Model of the Fermi Bubbles
Ilias Cholis, Leo Qiyuan Hu, Yi-Ming Zhong
We study the gamma-ray sky at high latitudes for energies between 0.3 and 900 GeV. We search for a contribution in the high-latitude sky and in the region of the Galactic Stellar H…
On the orbital eccentricities of primordial black hole binaries inside and outside of dark matter halos
Muhsin Aljaf, Ilias Cholis
Primordial black hole (PBH) binaries in the stellar mass range may still contribute a fraction of the detectable compact object binaries by LIGO and future GW observatories. PBH bi…
Limits on primordial black holes from the extragalactic gamma-ray background; current status and future projections
Ilias Cholis, Iason Krommydas, John Carlini
Primordial black holes (PBHs), possibly formed from the collapse of early universe perturbations, will evaporate via Hawking radiation with a lifetime comparable to the age of the…
Binary Black Holes population synthesis based on the current LVK observations
Mehdi El Bouhaddouti, Ilias Cholis, Muhsin Aljaf
The ongoing observations from ground based gravitational-wave observatories have led to the detection of more than a hundred merger events between black holes. We use the LIGO-Virg…
Galactic Center gamma-ray excess from a generic triaxial halo
Leo Qiyuan Hu, Ilias Cholis, Yi-Ming Zhong
Recent studies of Galactic surveys, such as Gaia, have revealed that the Milky Way's gravitational potential comes from a matter distribution that is triaxial and rotated with resp…
The Merger Rate of Primordial Black Holes
Muhsin Aljaf, Ilias Cholis
The merger rate of primordial black hole (PBH) binaries can be used to understand the source population of the merging black hole binaries observable through gravitational-waves (G…
GammaPBHPlotter: A public code for calculating the complete Hawking evaporation gamma-ray spectra from primordial black holes
John Carlini, Ilias Cholis
We present GammaPBHPlotter, a public Python code for calculating and plotting the Hawking radiation gamma-ray spectra of primordial black holes in the mass range of to $1…
Conservative limits on primordial black holes from the LIGO-Virgo-KAGRA observations
Mehdi El Bouhaddouti, Muhsin Aljaf, Ilias Cholis
Primordial black holes (PBH) may constitute a considerable fraction of dark matter. In this work we use the recent observations by the LIGO-Virgo-KAGRA (LVK) collaborations to set…
On the mass distribution of the LIGO-Virgo-KAGRA events
Mehdi El Bouhaddouti, Ilias Cholis
The merging black hole binaries detected by the LIGO-Virgo-KAGRA (LVK) gravitational-wave observatories, may help us shed light on how such binaries form. In addition, these detect…
Robustness of the Galactic Center Excess Morphology Against Masking
Yi-Ming Zhong, Ilias Cholis
The Galactic Center Excess (GCE) remains an enduring mystery, with leading explanations being annihilating dark matter or an unresolved population of millisecond pulsars. Analyzing…
