=== 同时段相关探测 ===
研究人员对于估计引力波产生的发生区域附近与引力波同时产生的无线电波、红外、可见光、X射线、γ射线等波段的电磁波以及中微子进行了后续探测<ref name="Properties" />。

==== 中微子 ====
对于中微子的探寻是由{{le|ANTARES|ANTARES (telescope)}}探测器及[[IceCube微中子觀測站]]合作进行的。ANTARES探测器在GW150914前后500秒内没有探测到可能的目标中微子，IceCube观测站则探测到了3个：一个是在南半天球找到的，另外两个则在北半天球。这与背景探测层次的预期相符。但这三个中微子中并没有一个产生于併合现象发生的90%置信区域内。<ref>{{cite web |language=en |first1=S. |last1=Adrian-Martinez |display-authors=etal |archivedate=2016-02-15 |archiveurl=https://web.archive.org/web/20160215165041/https://dcc.ligo.org/LIGO-P1500271/public/main |url=https://dcc.ligo.org/LIGO-P1500271/public/main |title=High-energy Neutrino follow-up search of Gravitational Wave Event GW150914 with ANTARES and IceCube |date=2016-02-12 |accessdate=2016-02-13 |publisher=LIGO Document Control Center Portal |deadurl=yes }}</ref>

==== 伽马射线暴 ====
[[费米伽玛射线空间望远镜]]的[[伽马射线暴]]监视系统在GW150914被检测到0.4秒后于其预估发生区域附近检测到一个强度约为{{val|50|u=keV}}的弱伽马射线暴。相关研究人员人员认为二者存在相关性，误报率为0.0022。如果二者确实相关的话，那么GW150914发生位置的90%信度区域大小则可降至{{val|199|u=deg<sup>2</sup>}}。<ref name="fermi_arxiv">{{cite arXiv|language=en|eprint=1602.03920|last1=Connaughton|first1=V.|title=Fermi GBM Observations of LIGO Gravitational Wave event GW150914|year=2016|class=astro-ph.HE|accessdate=2016-02-17|display-authors=etal}}</ref>依据[[国际伽玛射线天体物理实验室]]的全天反符合屏蔽光谱仪的观测结果，以伽马射线及硬X射线形式释出的能量不到以引力波形式释出的百万分之一。这一上限一定程度上排除了引力波与伽马射线暴之间的相关性。<ref name="Integral">{{cite arXiv|language=en|title= INTEGRAL upper limits on gamma-ray emission associated with the gravitational wave event GW150914|last=Savchenko |first=V.|last2=Ferrigno|first2=C.|last3=Mereghetti|first3=S.|display-authors=etal|class=astro-ph.HE|year=2016 |eprint= 1602.04180|accessdate=2016-02-19}}</ref>

依据目前对于黑洞併合的研究，在产生GW150914的双黑洞併合产生引力波时可能确实不会同时产生伽马射线暴，因为恒星质量双黑洞并不具有[[吸积盘]]。哈佛大学教授[[亚伯拉罕·勒布]]则试图通过另一种方式解释此次现象，以解释伽马射线暴的产生。他认为伽马射线暴的产生可能是由于此次黑洞併合发生在体量更大的母星中。一个高速自转大质量恒星在其坍缩时所产生的离心力所产生的旋转轴会令其变形为哑铃型，进而分裂为双黑洞。在这颗恒星坍缩过程的末尾会触发伽马射线暴。而之所以会存在0.4秒的延迟则是因为伽马射线暴在恒星星体中的传播速度较引力波传播速度稍慢。<ref name="fermi_woo">{{cite news|language=en|last1=Woo|first1=M.|title=LIGO’s black holes may have lived and died inside a huge star|url=https://www.newscientist.com/article/2077783-ligos-black-holes-may-have-lived-and-died-inside-a-huge-star/|accessdate=2016-02-17|work=New Scientist|date=2016-02-16|archive-date=2021-01-05|archive-url=https://web.archive.org/web/20210105101443/https://www.newscientist.com/article/2077783-ligos-black-holes-may-have-lived-and-died-inside-a-huge-star/|dead-url=no}}</ref><ref name="fermi_beall">{{cite news|language=en|last1=Beall|first1=A.|title=Ligo's black holes that helped prove Einstein's theory of gravitational waves could have been born inside a massive star|url=http://www.dailymail.co.uk/sciencetech/article-3450885/Ligo-s-black-holes-helped-prove-Einstein-s-theory-gravitational-waves-born-inside-massive-star.html|accessdate=2016-02-17|work=Daily Mail|date=2016-02-17|archive-date=2021-01-05|archive-url=https://web.archive.org/web/20210105101448/https://www.dailymail.co.uk/sciencetech/article-3450885/Ligo-s-black-holes-helped-prove-Einstein-s-theory-gravitational-waves-born-inside-massive-star.html|dead-url=no}}</ref><ref name="Loeb Draft">{{cite arXiv| language=en|title=Electromagnetic counterparts to black hole mergers detected by LIGO|year=2016|last=Loeb|first= A.|eprint=1602.04735|class=astro-ph.HE|accessdate=2016-02-19}}</ref><ref name="GRB on BBH">{{cite news|language=en|last=Gough|first=E.|url=http://www.universetoday.com/127463/did-a-gamma-ray-burst-accompany-ligos-gravitational-wave-detection/|title=Did a Gamma Ray Burst Accompany LIGO’s Gravity Wave Detection?|work=Universe Today|date=2016-02-18|accessdate=2016-02-19|archive-date=2016-02-20|archive-url=https://web.archive.org/web/20160220093949/http://www.universetoday.com/127463/did-a-gamma-ray-burst-accompany-ligos-gravitational-wave-detection/|dead-url=no}}</ref>

==== 其他波段电磁波 ====
[[雨燕卫星]]在引力波被探测到两天后对临近估计位置的星系进行了观测，并没有探测到可见光、紫外线以及X射线波段的电磁波<ref>{{cite arXiv|language=en|last1=Evans|first1=P. A.|eprint=1602.03868|title=Swift follow-up of the Gravitational Wave source GW150914|class=astro-ph.HE|year=2016|accessdate=2016-02-13}}</ref>。
