Population synthesis of Galactic middle-aged pulsar wind nebulae I. Detection prospects for current and future instruments

A. De Sarkar, D. F. Torres, B. Olmi +2

Pulsar wind nebulae (PWNe) constitute the largest population of Galactic very-high-energy (VHE; GeV) -ray sources and are key laboratories for studying particle accele…

Population synthesis of Galactic middle-aged pulsar wind nebulae II. Observational signatures of superefficiency

D. F. Torres, A. De Sarkar, B. Olmi +2

Pulsar wind nebulae (PWNe) interacting with the host supernova remnants (SNRs) can enter the reverberation phase in which reverse-shock-driven compression amplifies the magnetic fi…

Temporal evolution of the periodic GeV signal from 4FGL J1913.2+0512 and analysis of the SS 433 / W50 lobes

Ömer Faruk Çoban, Diego F. Torres, Jian Li +3

SS 433 is a microquasar whose relativistic jets precess every ~162 days, providing a laboratory for jet-interstellar medium interactions. We present a comprehensive analysis of 16…

Dissecting the emission from LHAASO J0341+5258: implications for future multi-wavelength observations

Agnibha De Sarkar, Pratik Majumdar

The Large High Altitude Air Shower Observatory (LHAASO) has detected multiple ultra-high energy (UHE; E 100 TeV) gamma-ray sources in the Milky Way Galaxy, which are associa…

Lepto-hadronic interpretation of 2021 RS Ophiuchi nova outburst

Agnibha De Sarkar, Nayana A. J., Nirupam Roy +2

Very high energy (VHE; 100 GeV E 100 TeV) and high energy (HE; 100 MeV E 100 GeV) gamma-rays were observed from the symbiotic recurrent nova RS Ophiuchi (RS O…

Supernova connection of unidentified ultra high energy gamma-ray source LHAASO J2108+5157

Agnibha De Sarkar

We present a simple phenomenological model of hadronic interaction between protons accelerated in an old supernova remnant (SNR) and cold protons situated within the associated mol…

Exploring the hadronic origin of LHAASO J1908+0621

Agnibha De Sarkar, Nayantara Gupta

Recent observations by the Large High Altitude Air Shower Observatory (LHAASO) have paved the way for the observational detection of PeVatrons in the Milky Way Galaxy, thus revolut…

Galactic molecular clouds as sources of secondary positrons

Agnibha De Sarkar, Sayan Biswas, Nayantara Gupta

Secondary positrons produced inside Galactic Molecular Clouds (GMCs) can significantly contribute to the observed positron spectrum on Earth. Multi-wavelength data of GMCs are part…
