• The Evolution of a Structured Relativistic Jet and Gamma-Ray Burst Afterglow Light Curves (2003, methodology): “…of the emergent jet, the density of the medium in the immediate vicinity of the GRB, etc., is that of comparing the observed afterglow light curve with the theoretically calculated flux (Wijers & Galama 1999; Granot, Piran, & Sari 1999b; Chevalier & Li 2000; Panaitescu & Kumar 2001a, 2001b, 2002).”
• The Rates of Hypernovae and Gamma-Ray Bursts: Implications for Their Progenitors (2004, background): “This factor depends on the jet opening angle, and is typically estimated as ∼ 50 – 500 (Frail et al. 2001; Panaitescu & Kumar 2001).”
• The Collimation-corrected Gamma-Ray Burst Energies Correlate with the Peak Energy of Their νFν Spectrum (2004, methodology): “This was also confirmed independently by Panaitescu & Kumar (2001a).”
• Theories of Gamma-Ray Bursts (2001, background): “Its effects on afterglows were considered by (Waxman 1997b), and observational manifestations in afterglows were investigated more carefully by Panaitescu & Kumar 2000 and Sari & Esin 2001.”
• AFTERGLOW OBSERVATIONS OF FERMI LARGE AREA TELESCOPE GAMMA-RAY BURSTS AND THE EMERGING CLASS OF HYPER-ENERGETIC EVENTS (2010, background): “…continuous improvements and it has been well tested (Meszaros & Rees 1997; Sari et al. 1998, 1999; Wijers & Galama 1999; Chevalier & Li 2000; Panaitescu & Kumar 2000; Yost et al. 2003; Willingale et al. 2007), it still must make several simplifying assumptions about the shock dynamics,…”
• Probing the cosmic reionization history and local environment of gamma‐ray bursts through radio dispersion (2003, background): “The isotropic equivalent (i.e. beaming-corrected) initial kinetic energy of the blastwave is fiducially E = 1053 erg from the most recent observational determinations (Panaitescu & Kumar 2001, 2002, Frail et al. 2001).”
• Evidence for a Canonical Gamma-Ray Burst Afterglow Light Curve in the Swift XRT Data (2005, background): “…taking into account radiative losses, while most previous estimates of E /E0 included the radiative losses assuming that they decrease the energy of the afterglow shock by a factor of 3 or more (Panaitescu & Kumar 2001a, 2001b; LloydRonning & Zhang 2004; A. Panaitescu 2005, private communication).”
• High-Energy Spectral Components in Gamma-Ray Burst Afterglows (2001, background): “Extensive efforts have been made to determine key fireball parameters such as E , ǫB , ǫe, n using snapshot spectral fits extending from radio to X-rays on well studied GRB afterglows (e.g. Galama et al. 1998; Wijers & Galama 1999; Panaitescu & Kumar 2001).”
• Testing the Standard Fireball Model of Gamma-Ray Bursts Using Late X-Ray Afterglows Measured by Swift (2006, background): “…et al. 2003, Hjorth et al, 2003) and multiwavelength observations and analysis of this bright afterglow and similar events (Harrison et al. 2001, Panaitescu & Kumar 2001, 2002, 2003, Willingale et al. 2004) established that afterglows were broadly consistent with the expected synchrotron…”
• Supernova hosts for gamma-ray burst jets: dynamical constraints (2002, result): “These authors derive gamma-ray energies reminiscent of supernovae: roughly 3 × 1050 erg for the observed lobes of GRBs. Similar results were reported by Panaitescu & Kumar (2001) and Freedman & Waxman (2001).”
• Asymmetric Supernovae from Magnetocentrifugal Jets (2001, background): “This scenario of jet collisions does not help to resolve the issue of the low afterglow densities associated with some - ray bursts (Panaitescu & Kumar 2001; Scalo & Wheeler 2002b) that are difficult to achieve in any model based on a massive star that expels a substantial wind.”
