Bill In Honor Of Sean Collier Would Grant Federal Death Benefits To

first_imgWILMINGTON, MA — A bill named in honor of Wilmington fallen hero Sean Collier is making its way through the U.S. House of Representatives.If passed, the Officer Sean Collier Campus Police Recognition Act would allow the families of police officers — employed at PRIVATE colleges and universities — that are killed in the line of duty to receive death benefits from the federal government.Currently, only the families of sworn law enforcement officers at PUBLIC colleges and universities are eligible for these benefits.“Officer Sean Collier was shot and killed while on duty on the campus of the Massachusetts Institute of Technology (MIT) in April 2013 by the Boston Marathon Bombers,” reads a statement from the International Association of Campus Law Enforcement Administrators. “Because MIT is a private, non-profit institution of higher education, his family is not eligible for [Public Safety Officer Benefits] assistance. Had Officer Collier been employed by a public college or university, his family would have been eligible for assistance. In fact, had an officer with the city police department been killed alongside Officer Collier, the city officer’s family would have received [Public Safety Officer Benefits] assistance.”According to the Association, since 1923, 46 university police officers have been killed in the line of duty — 34 at public institutions eligible to receive the death benefit and 12 private institutions not eligible to receive the death benefit.“Congress passed the Public Safety Officers Benefit Act to provide peace of mind to aspiring police officers by assuring them that their families would be cared for in the event they gave their life in service to others,” according to the statement. “As a matter of basic fairness, this peace of mind should be given to all sworn law enforcement officers regardless of which agency employs them.”The Officer Sean Collier Campus Police Recognition Act of 2019 (H.R. 816) has bipartisan support in the U.S. House of Representatives. The bill, sponsored by Peter King (R-New York), already has 15 co-sponsors, including Massachusetts representatives Seth Moulton, Richard Neal, Stephen Lynch, Bill Keating, Joe Kennedy, Katherine Clark, James McGovern, and Lori Trahan.The bill was introduced in the House on January 28, 2019. It was immediately referred to the Judiciary Committee. On March 25, 2019, the bill was referred to Judiciary’s Subcommittee on Crime, Terrorism and Homeland Security.Like Wilmington Apple on Facebook. Follow Wilmington Apple on Twitter.

Xray study sheds more light into the nature of a gammaray pulsar

The study, based on X-ray observations, sheds more light into the nature of this peculiar object and its pulsar wind nebula (PWN). Results of the research were presented in a paper published June 3 on arXiv.org. 3 arcmin × 3 arcmin Chandra X-ray image of the pulsar vicinity in 0.5–10 keV range smoothed with a 25 pixel Gaussian kernel.

Some of them also showcase radio emission that is often difficult to detect. This is most probably because their narrow radio beams miss the sightline towards Earth.However, some gamma-ray pulsars are completely radio-quiet, which means that observations in other regimes, for instance, in X-ray wavelengths, are needed to learn about their properties. In particular, X-ray studies of such objects have the potential to reveal their pulsar wind nebulae (PWNe) and associated supernova remnants (SNRs), which could provide important information about pulsar parameters and interaction of relativistic pulsar winds with the ambient medium.With that aim in mind, a team of Russian astronomers from the Ioffe Institute in St. Petersburg, Russia, led by Anna V. Karpova, decided to analyze archival X-ray data obtained by XMM-Newton and Chandra spacecraft. The target of their studies was a young and energetic radio-quiet pulsar designated PSR J1826−1256. Located most likely some 4,320 light years away from the Earth, PSR J1826−1256 is about 14,000 years old, has a period of 110.2 milliseconds, a spin-down luminosity of around 3.6 undecillion erg/s and a surface magnetic field of approximately 3.7 trillion G. Based on these parameters, the object was classified as a Vela-like pulsar. Moreover, previous observations have shown that PSR J1826−1256 hosts a faint, but remarkably long trail-like PWN connected to the pulsar and extending south-west from it.The new study published by Karpova’s team provides more insights into the nature of PSR J1826−1256 and a PWN associated with it.”Here we report the simultaneous X-ray analysis of archival XMM-Newton and Chandra observations of PSR J1826−1256 and its PWN,” the astronomers wrote in the paper.The study found that the spectrum of PSR J1826−1256 can be described by the power-law model with a photon index of about 1.0 and that the PWN spectrum becomes softer with the distance from the pulsar, what is indicative of synchrotron cooling.When it comes to the PWN, the analysis revealed that it appears to be a mixed-type morphology nebula containing a torus, jets and a trail. XMM-Newton and Chandra images show that one of the jets is bent by the ram pressure, due to the pulsar proper motion vector not coinciding with the jet direction. The researchers noted that such geometry explains the PWN morphology and also suggests that it could be associated with a recently detected SNR candidate named G18.45−0.42.The study also found that PSR J1826−1256 is located much farther away than previously thought. New estimates made by the team indicate that its distance to our planet is approximately 11,400 light years. Astronomers investigate pulsar wind nebula DA 495last_img read more
