First Binary Pulsar Research Paper

Luis Walter Alvarez was born on June 13th in the year 1911 in San Francisco but at that time no one knew he was going to be a world renowned physicist. As a adolescent, his love for science, technology and machines was evident, but no one guessed he would make something out of it. He and his father (Walter C. Alvarez) built a radio when he was eleven, this was when the radio was still a new invention. Graduating from The University of Chicago in 1932 and earning his phD in 1936 was not the end of his scientific interest. Luis Walter Alvarez continued to study science and physics. He was credited with many necessary discoveries about subatomic particles for which he earned the Nobel Prize in physics. His work did not stop there. He was a co-developer in the creation of the “ground-control approach system” for aircraft during the 1940’s. Luis Walter Alverez had a very significant role in the development Manhattan Project, in which he suggested the technique used for the detonation of an atomic bomb. He was member of the National Inventor's Hall of Fame. On top of all this he held ownership of the patents for over 30 inventions including radar systems and the bubble chamber.

William Herschel was a musician and an astronomer. The motivation that drove William Herschel to the discovery of Uranus was his obsession with astronomy and the heavens. He charted the stars with a telescope he built himself, he then discovered a “comet” which really was the planet Uranus, but he initially didn’t realize it. He noticed the “comet” had moved and decided that his annotations on the position of the “comet” had been written down incorrectly. Herschel wanted to know the dimensions, and position of the “comet”. He carefully measured the location and diameter of the comet for some time and discovered its journey as parallax to “our side of the sun” on a daily basis. In 1782 Herschel finally called the comet his planet. The knowledge

In March of 1781 William Herschel, a musician and amateur astronomer discovered what would eventually be called “Uranus.” He discovered what he initially thought was a comet, while looking for what he called double stars. He ended up finding Uranus as it passed by one of the stars he was looking at. He recorded is in a journal, and after a few days looked for it again. He was able to see that it was moving and that it appeared to have an orbit. He contacted some friends of his that were astronomers and gave them the work that had done and wanted to them to explore it further than he could. They ended up finding the same thing and also classifying it as a comet, probably a comet called 1770, and congratulating him on his discovery. It wasn’t

MAGIC telescopes observed BL Lacertae in 3 consecutive nights for duration of 1 hour per night, under excellent weather conditions. The MAGIC observations were triggered by the high activity measured at optical and gamma-ray energies. The source is active in the high energy gamma-ray band as seen by Fermi-LAT. Roughly 40 BL Lac objects are known. Perhaps the most obvious property of BL Lac objects is that they look like stars. Unlike most stars, BL Lac objects are very strong sources of radio and infrared emission. This emission, which is called synchrotron emission, arises from electrons traveling near the speed of light in spiral paths in strong magnetic fields. Synchrotron emission generally is polarized, so BL Lac objects have polarized emission. When light or other electromagnetic radiation is polarized, the directions of the oscillations are the same. The amount of polarization and the brightness of BL Lac objects is highly variable. This variability is very rapid and erratic. They can change very significantly in times as short as 24 hours or less. The rapid variability tells us that the energy source is very small. Nothing can travel faster than the speed of light, including whatever signal or mechanism causes the BL Lac object to change its

This allowed, for the first time, to accurately determine Pluto’s mass and diameter (Putnam). However, during this time, even the U.S. Naval Observatory Flagstaff Station located on the outskirts of town was being taking over by the overpowering monster of light emanating from city streets.

The only reason this happened was because he was close with the church since his uncle was a bishop. In 1596 German Astronomer David Fabricius discovered the variability of the star Omicron Ceti, later named Mira or the Wonderful Star, probably making it the first non-nova, non-supernova variable star to be recognized as such (Langley, 46). In 1638, Johann Holwarda determined the period of variability of this prototypical pulsating red giant star to be about 11 months. This fainter star is immersed in and presumably accreting material from the red giants stellar wind. Mira, unlike most red giants, is in fact a weak X-ray source, and Jura and Helfand suggested that the emission is related to this wind-star interaction.

Elizabeth Gibney discusses the history of fast radio bursts and astronomer’s strategy to finding them in the universe in her article, “Fast Radio Bursts are Astronomy’s Next Big Thing.” She begins by defining fast radio bursts as “fleeting blasts of energetic cosmic radiation of unknown cause.” (Gibney) Gibney briefly reviles that even though FBRs were discovered a decade ago, the phenomenon has just recently been accepted as genuine.

Frederick William Herschel was a British astronomer and composer. In 1774 he constructed his first telescope with which he spent the next 9 years studying the sky. After the completion of several catalogues, on March 13, 1781, he made an amazing discovery. The planet Uranus. This was an extraordinary discovery, and because of it, Herschel was made Court Astronomer by King George the Third, which was indeed a great honor. Later on he became the first President of the Royal Astronomer Society, in 1820. One of the key people leading to his Astronomy breakthroughs was Reverend John Michell, who was making ground-breaking views on astronomy and the construction of telescopes. Michell and Herschel met, as Herschel was a composer, and Michell was

The moons we know today were also discovered by Herschel: Titania and Oberon. After two years, in 1789 William also finished his largest telescope, 48 inches. This telescope made another Saturn’s sixth and sevenths moon; Enceladus and Mimas. Now moving on from the telescope, William tried out a basic experiment determining the temperature of different colors passing through a prism. He began to notice light that was beyond the color red. Higher then light and the visible spectrum. Using measurements and prior knowledge the light he was seeing is what we know today, Infrared radiation. The European Space Agency infrared space observatory was subsequently named for him.

William Herschel began looking into the heavens as a hobby, he worked regularly in music and only dabbled in astrology in his free time. He was frustrated with the inability to see things as clearly as he liked and it led him to develop a better telescope than was available at the time. He worked and created a better scope and by that was able to study the stars and five planets. The planets did not interest him as much as how the stars and such are formed. His main interests were in how things were created. He studied the clusters of stars. As he was able to see better and was able to chart the things he saw, he was able to notice and take note of Uranus. In the beginning, he believed it to be a comet, and reported it to astrologers in England. Their equipment was insufficient to see the “comet”. As they continued to watch they could document that it was indeed not a comet.

The discovery of Uranus on March 13th in 1781 by William Herschel was an accident. He was using his 7ft reflector telescope. He had talked to Joseph Priestly and John Mitchell about the construction. It started as a survey of the stars to “isolate as many double stars as he could discover”. When he spotted Uranus he thought it was a comet.

Planets have mass and therefore have an effect on their stars orbit causing it to wobble. The wobble in the case of a pulsar star is seen as the periodic delay in the arrival of the pulses from the pulsar star (Wolszczan 1994). Due to the nature of a Pulsar star we can detect perturbations in its orbit through its pulses but to detect perturbations in other stars orbits, astronomers use a stars radial velocity.
