Es führt zudem einige der empfindlichsten Suchen nach kontinuierlichen Gravitationswellen von unbekannten Neutronensternen in den Daten von <span class="h-card" translate="no"><a href="https://astrodon.social/@LIGO" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>LIGO</span></a></span> durch. Der Nachweis dieser Wellen würde ein neues astronomisches Instrument liefern, um Schwerkraft und Materie unter Extrembedingungen und die fundamentale Physik zu untersuchen.</p><p>ℹ️ <a href="https://www.aei.mpg.de/1226909/happy-20th-birthday-einstein-home" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">aei.mpg.de/1226909/happy-20th-</span><span class="invisible">birthday-einstein-home</span></a></p><p>➡️ Mitmachen unter <a href="https://einsteinathome.org/de/join" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">einsteinathome.org/de/join</span><span class="invisible"></span></a></p><p><a href="https://astrodon.social/tags/20YearsOfEinsteinAtHome" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>20YearsOfEinsteinAtHome</span></a> <a href="https://astrodon.social/tags/OnThisDay" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OnThisDay</span></a> <a href="https://astrodon.social/tags/OTD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OTD</span></a> <a href="https://astrodon.social/tags/CitizenScience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CitizenScience</span></a> <a href="https://astrodon.social/tags/DistributedComputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DistributedComputing</span></a> <a href="https://astrodon.social/tags/Neutronensterne" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Neutronensterne</span></a> <a href="https://astrodon.social/tags/Gravitationswellen" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Gravitationswellen</span></a> <a href="https://astrodon.social/tags/Pulsare" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Pulsare</span></a></p>
MPI for Gravitational Physics<p>🥳 Happy 20th birthday, Einstein@Home!&nbsp;🎉 </p><p>The distributed volunteer computing project was launched on this day in 2005.</p><p>Since the launch of <span class="h-card" translate="no"><a href="https://academiccloud.social/@einsteinathome" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>einsteinathome</span></a></span> on 19&nbsp;February 2005, nearly half a million participants from around the world have donated idle computing time on their PCs and smartphones to search for astrophysical signals from spinning neutron stars – small, massive, and exotic remnants of exploded stars. </p><p>Einstein@Home is one of the world’s largest volunteer computing projects and a scientific success story: It has discovered more than 90 new neutron stars, some of them very unusual, through their radio and gamma-ray pulsations. It is also conducting some of the most sensitive searches for continuous gravitational waves from unknown neutron stars in <span class="h-card" translate="no"><a href="https://astrodon.social/@LIGO" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>LIGO</span></a></span> data. Finding the elusive waves would provide a new astronomical tool for studying extreme gravity and matter and fundamental physics.</p><p>ℹ️ <a href="https://www.aei.mpg.de/1226437/happy-20th-birthday-einstein-home" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">aei.mpg.de/1226437/happy-20th-</span><span class="invisible">birthday-einstein-home</span></a></p><p>➡️ Join the fun at <a href="https://einsteinathome.org/join" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="">einsteinathome.org/join</span><span class="invisible"></span></a></p><p><a href="https://astrodon.social/tags/20YearsOfEinsteinAtHome" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>20YearsOfEinsteinAtHome</span></a> <a href="https://astrodon.social/tags/OnThisDay" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OnThisDay</span></a> <a href="https://astrodon.social/tags/OTD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OTD</span></a> <a href="https://astrodon.social/tags/CitizenScience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CitizenScience</span></a> <a href="https://astrodon.social/tags/DistributedComputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DistributedComputing</span></a> <a href="https://astrodon.social/tags/NeutronStars" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NeutronStars</span></a> <a href="https://astrodon.social/tags/GravitationalWaves" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GravitationalWaves</span></a> <a href="https://astrodon.social/tags/Pulsars" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Pulsars</span></a></p>
